Question

Propose structures for molecules that meet the following descriptions:

 (a) Contains two sp²-hybridized carbons and two sp³-hybridized carbons 

 (b) Contains only four carbons, all of which are sp²  -hybridized

 (c) Contains two sp-hybridized carbons and two sp² -hybridized carbons

Step-by-Step Solution

Answer

(a)

                             A carbon atom with and hybridization

(b)

                              Carbon atom with sp² hybridization

(c)

                             Carbon atom with sp and sp² hybridization

Hybridization of carbon

The table below depicts the hybridization of carbon for different types of bonds formed

Bonds Formed	Hybridization
4 single bonds	sp3
2 single bonds and 1 double bond	sp2
1 single bond and 1 triple bond	sp
2 double bonds	sp

a) Two sp 2 hybridized carbon and two sp 3 hybridized carbons

Some possible structures of molecules with sp² hybridized carbons and two sp³ hybridized carbons are represented as:

Carbon atom with sp² and sp³  hybridization

(b) 

Carbon atom with sp²  hybridization

) Some possible structures of molecules that contains two hybridized carbon and two hybridized carbon are shown as follows

                       Carbon atom with sp and sp²    hybridization
