Question : 31 of 88

Marks: +1, -0

Give the structural formula of the following organic compounds:
1. 2-chlorobutane
2. Methanal
3. But-2-yne

Solution:

(1)

{\H} - {\C}↖{| }↖{\H}↙{ | }↙{\H}- {\C}↖{| }↖{\H}↙{ | }↙{\H}- {\C}↖{ |}↖{\H}↙{ | }↙{\H}- {\CH}_3

2-chlorobutane

( {\CH}_3 {\CH}_2 {\CHCl} {\CH}_3)

(2)

\H-\C↙{|}↙{\H}=\O

(HCHO)
Methanal
(3)

{\H}- {\C}↖{|}↖{\H}↙{|}↙{\H}- {\C} ≡ {\C}- {\C}↖{|}↖{\H}↙{|}↙{\H}- {\H}

But-2-yne

( {\CH}_3- {\C} ≡ {\C}- {\CH}_3)
