A straight chain hydrocarbon has two carbons that are bonded to only one other carbon (the terminal carbons). A branched chain hydrocarbon has more than two carbons that are bonded to only one other carbon (the terminal carbons at the ends of each branch). A cycloalkane (cyclic hydrocarbon) has no carbons that are bonded to only one carbon - the chain is hooked back to itself.

Branched chain do have ramification, it have branches.

What advantage does the branched-chain structure of glycogen provide compared with a straight chain of glucose?
There are several advantages because the glycogen molecule is branched. It is a better storage facility for glucose because the branches make it more soluble, and the glycogen is also synthesized more quickly.
Is kerosene saurated?
Kerosene is saturated, because it only contains single carbon-carbon covalent bonds. Kerosene is actually a mixture of more than one straight-chain or branched alkane hydrocarbons, but none of them feature double or triple bonds, so the Lewis structure indicates it is saturated.
What does more viscous mean?
Have a look here http:/dictionary.reference.com/browse/viscousViscosity it how thick or thin a fluid is.The thicker a fluid is the more viscous. If the fluid is less viscous it is thinner. A fluid is liquid AND gas. If a fluid is hotter is gets less viscous but if it is cooler it will be more viscous.
Why is it harder to move through a vicous liquid?
the viscous force is directly proportional to the viscosity of the fluid. so the more viscous a liquid is, more the viscous force and harder it is to move for a bod through it.
Is Ostwalds viscometer used to measure viscosity of more viscous oil?
Yes, the Ostwalds viscometer can be used to measure the viscosity of more viscous oil.
Do isomers boiling points increase or decrease with more branching?
Straight chain isomers have higher boiling points, so the more branched the isomer the lower the boiling point.
Is a short-chain hydrocarbon more viscous than a long chain hydrocarbon?
Typically the shorter the carbon chain, the LESS viscous the hydrocarbon. The longer the chain, the MORE viscous the hydrocarbon. For example consider the viscosity and molecular size in: Gasoline < Diesel < Motor Oil < Tar Viscosity increases with the molecular size and length of hydrocarbon chain.
How does chain length of alcohols affect viscosity?
The longer the chain length, the more viscous the alcohol

What metabolic distinction is associated with branched chain amino acids as compared to other essential amino acids?
The branched amino acids is used by the organism in protein where the polypeptide chain should be branched, other than that i think they're more or less just involved in transamination reaction and aminoacid-biosynthesis
What is a branched hydrocarbon?
Branched hydrocarbons are structural isomers, this means that they have the same chemical formulas but are in a different configuration. For example take butane with its formula C4H10 this also be written as CH3CH2CH2CH3 this is called the structural formula. You could use this to draw out and you would have the structure of butane. And this configuration is simply called a straight chain due to the way it looks. However with a branched chain it doesn't look like a straight chain, it would look like a straight chain with a 'branch' off it. This is because a carbon atom has moved its location. But the moving of the carbon does not effect how many carbons there are overall. So to draw a branched chain you would use this structural formula;H CH3CH(CH3)2 - the brackets mean that there are two lots of them coming of the CH group. This is called iso-butane or 2-methlypropane. This is a branched chain, and if you draw the butane out then drawn iso-butane next to it you will see where they get the names from. As well as the structure being different, they have different properties such as boiling point, this is because branched chains do not 'pack' as tightly together as straight chains, think about a pack of cards for the straight chains - they lie flush together with not real space this is what is meant by packing. However with the branch chains they don't pack as neatly together so imagine some of the cards are folded and prop the others up so they don't fit snugly. Because of this they don't have as much attraction to each other through the Van der Waals, and have a lower attraction to each other. This means that when heat is applied they can't hold together as well thus leading to a lower boiling point.
Which is more viscous pure water or saline water?
The saline water is more viscous.
Why n-pentane has higher melting point than neopentane?
It is because n-pentane is a straight chain hydrocarbon meaning it has more surface area to reach the boiling point, neopentane has significantly less surface area that's why it will boil quicker than n-pentane. The more branched molecule, the lower is its boiling point will be & the less branched molecule, the higher its boiling point will be. For combustion energy the opposite holds true, the more branched molecule has a higher energy than an unbranched one.Hope You Like My Answer...By rananeeraj168@gmail.com in facebook
Is water more viscous than vegetable oil and methylated spirits?
Water is more viscous than methylated spirits, and vegetable oils are more viscous than water.
Define volatile and viscous?
Viscous means how thick a LIQUID is and how tightly the particles are packed together if the liquid is thick(less runny) it is more viscous if the liquid is thin(more runny) it is less viscous
Amylopectin has what characteristics?
Amylopectin is a branched-chain polymer of glucose that is a component of starch, characterized by frequent branching points that create a highly branched structure. It can be broken down into glucose units for energy more quickly than amylose due to its branched structure. Amylopectin is less prone to retrogradation compared to amylose, making it more suitable for applications where a gel-like consistency is desired.
What is the difference between a short-chain and a long-chain hydrocarbon?
short chain hydrocarbons have a low boiling and melting point whereas high chain hydrocarbons have a higher boiling and melting point. Also, short chain hydrocarbons have a low density and higher ones have a higher density. :)
