Question

Which of the straight chain compounds from A and B is saturated and unsaturated straight chains
2)Name these straight chains
3)Write the chemical formula and number of -CH2- units.​

Answer 1

Answer:

1) A-saturated   B-unsaturated

2) A-Propane    B-Prop-1-ene

3) A-C3H8 {CH3CH2CH3}, therefore, no. of ch2=1

    B-C3H6 {CH3CHCH2}, therefore no. of ch2=1

Good luck :))

Answer 2

Answer:

a) propane unsaturated

b) propene saturated

3) formula by a -CH2- unit is called a homologous series
