PROPANE. Structurally it is 'CH3-CH2- CH3'.

NB

#1 The 'prop' moiety indicates that there are three(3) carbons.

#2 the 'ane' moiety indicates that it is an Alkane.

NNB

The root names from Latin for the given number of carbons in the chain are

#1 ; meth

#2 ; eth

#3 ; Prop

#4 ; But

#5 ; Pent

#6 ; Hex

#7 ; Hept

#8 ; Oct

#9 ; Non

#10 ; Dec

NNB

The functional groups are indicated by

Alkane ; -Ane ( Single bond between two adjacent carbons)

Alkene ; -Ene (Double bond between two adjacent carbons ).

Alkyne ; -Yne (Triple bond between two adjacent carbons. ).

e.g.

PropEne ; CH2=CH-CH3

PropYne ; HC///C-CH3

The indicated capital letter is critical in the correct naming of hydrocarbons.

What is the formula for the alkane containing 100 hydrogens?

The alkane with 100 hydrogen would be C49H100.The 100 hydrogen will have 49 carbons attached.The carbons on the ends would have 3 hydrogen each so the hydrogen left are 94 so the Carbon in the chain can only have 2 hydrogen each.Therefore the no of hydrogen in between will have 47 carbons and two carbons on the end. 47+2 =49 carbons.


What is the condensed structural formula for an alkane with four carbon atoms?

C10H22 It is a chain of 7 carbons, with a branch on the 4th carbon, that branch is 3 carbons long.


Is 3-heptene an alkane alkene or an alcohol?

The name of 3-heptene gives it away, for alkenes end in -ene. Heptene is a carbon chain of 7 carbons, and alkenes have a double bond between carbons at the noted carbon (3), so this double bond is between C3 and C4, and the chain is otherwise completely hydrogenated. You might write the structure as: CH3CH2CH=CHCH2CH2CH3


In alkanes carbon is bonded to how many other atoms?

Four. A terminal carbon in an alkane is bonded to 3 hydrogens and 1 carbon, while a middle carbon is bonded to 2 hydrogens and 2 carbons.

Is 2-methylpentane an alkane alkene or an alcohol?

Yes but you have to draw it as a 3 carbon ring structure (like a triangle) and the 1st carbon would have a CH3 and an OH.


How many covalence bond in propane?

There are 9 covalent bonds in propane. Propane is a three-carbon alkane molecule, with each carbon forming four covalent bonds (3 with other carbons, 1 with hydrogen).


What is formula for alkane?

The general formula for an alkane is CnH2n+2, where n is the number of carbon atoms in the alkane molecule. Alkanes are saturated hydrocarbons composed only of carbon and hydrogen atoms bonded together by single covalent bonds.

Is 3-methyloctane an alkane an alkene or alcohol?

3-methyloctane is an alkane because it consists entirely of carbon-carbon single bonds. Alkanes are hydrocarbons made up of only single bonds.
