Question

(a) Which of the straight chain
compounds from A and B is
saturated and unsaturated straight
chains.
(b) Name these straight chains.
(c) write their chemical formula and number of -CH2- units.​

Answer 1

Answer:

chain A is saturated

propane is A and B is propene

CH3 CH2 CH3

CH3 CH-_CH 2

Answer 2

The answers are as follow:---

a)chain A is saturated compound whereas chain B is unsaturated as.

●saturated compounds have only single bond and valency of all carbon satisfied with different elements.

●unsaturated compounds have double or triple bond so give addition reaction as scope of addition of elements.

b)the chainA is three carbon alkane so name is propane,whereas chain B is alkene with double bond at first carbon so name is prop-1-ene.

c)chemical formula of compound A is CH3CH2CH3.and it has one CH2 unit.

Chemical formula of compound B is CH3CHCH2 and it also has one CH2 unit.
