Hi, in this answer we are going to arrange the fatty acids in the order of highest melting point to lowest melting point.
00:15
Fatty acids are long chains of carbon atoms attached to hydrogen atoms which have carboxy group at one end.
00:27
So that is why it is termed as an acid.
00:30
So, fatty acids are of two type, namely saturated fatty acids and unsaturated fatty acids.
00:40
Saturated fatty acids do not have doubled or triple bonds in their structure, while unsaturated fatty acids have one or more double or triple bonds in their structure.
00:59
Saturated fatty acids have a higher melting point when compared to the unsaturated fatty acids because unsaturated fatty acids have double or triple bonds in their structures which provides kings in their structure and decreases the attraction between the atoms of the fatty acid chain.
01:29
So when you compare among the saturated fatty acids, the saturated fatty acids with more number of carbon atoms have higher melting point and among the unsaturated fatty acids, these fatty acids which have more number of double bonds have lesser melting point.
01:56
So here out of the given options a and c are saturated.
02:02
Fatty acids so they will be decided based on the number of carbon atoms and d and d are unsaturated fatty acids so they'll be decided on the base of number of double bones...
