All fats contain chains of carbon atoms bonded to hydrogen atoms. In a saturated fat the carbon atoms in the chains are boned to as many hydrogen atoms as possible (that is, 2 each, with the last carbon bonded to 3) and all carbon-carbon bonds are single bonds. In an unsaturated fat some of the carbons are not bonded to the maximum number of hydrogen atoms, and those carbon atoms that are missing hydrogen atoms are double bonded to a neighboring carbon.
a hydrocarbon that has double bond or triple bond between two carbons
Because the unsaturated fats contains double bonds between some of the carbons, saturated fats only contain single bonds between all of the carbons. The double bonding gives the molecules a different goemetry.
Formaldehyde, H2C=O, is the basic member of organic compounds known as aldehydes. Aldehydes are hydrocarbons (chains of carbons with hydrogen attached) with an oxygen atom double-bonded to a carbon.
- Cyclobutane: four carbons single-bonded in a square pattern, each with two hydrogens. H2C----CH2 | | H2C----CH2 - 1-butene: four carbons in a chain with a double bond between the first and second carbons: H2C==CH--CH2--CH3 - 2-butene: four carbons in a chain with a double bond between the second and third carbons: H3C--CH==CH--CH3
no
One Arene and two Imides The arene is the alternating double bonded carbon ring on the left, while the Imides are each a nitrogen with two carbons and another bond, where the carbons each have double bonded oxygens.
Propene is a linear hydrocarbon containing 3 carbons and 6 hydrogens. Two of the carbons are double bonded. Starting at the double-bonded end, you have two hydrogen atoms bonded to the end carbon, then a single carbon double bonded to the first carbon and with a single hydrogen bonded to it, then the third carbon is singly bonded to the second with 3 hydrogen atoms bonded to it.Propene is also known as propylene or methyl ethylene.
Just the difference between cis and trans isomers. The arrangement of functional groups around double bonded carbons. Same groups lined up on the same side are cis fatties and alternate groups lined up on the different sides are trans fatty acids.
Think of this as H2C3H2 or HC3H3 As carbon is tetravalent and hydrogen is monovalent there must be either two hydrogens bonded to a carbon that is double bonded to another that is double bonded to the third which has the remaining hydrogens double bonded. Otherwise this must be a hydrogen bonded to a carbon that is triple bonded to another carbon which is single bonded to the third carbon which is bound to three hydrogens.
alkane
ethene (also called ethylene). It is kind of "H" shaped. It has 2 carbons, double bonded, and four hydrogen singly bonded to those. 2 per carbon.
To solidify them by adding hydrogens which straighten out the double bonded carbons from their kinking so that the pack well and solidly. ( butter, for instance )

CH3-CH=CH-CH2-CH2-CH2-CH3 if hydrogen of doble bonded carbons are at the same side of plane of double bond then it is cis isomer....
Saturated fats contain only single bonds between carbons, whereas unsaturated fats contain at least one double bond.
