A) C4H8O
B) C3H8O
C) C3H6O2
D) C4H10O

Answer 1

Answer:

Option B)CH3H8O is correct

Answer 2

Dear Student,

◆ Answer -

(A) C4H8O

● Explanation -

Structural formula of propane is CH3-CH2-CH3. If H-atom is replaced by -CO-H group, structural formula will be CH3-CH2-CH2-CO-H.

Propane has molecular formula C3H8. If H-atom is replaced by -CO-H group, molecular formula will be C4H8O.

Hope this helps you. Thanks dear...
