MediumWhat are the hybridisation states of each carbon atom in the following compounds?
$CH_2=C=O, \quad CH_3-CH=CH_2, \quad (CH_3)_2CO, \quad CH_2=CH-CN, \quad C_6H_6$
$CH_2=C=O, \quad CH_3-CH=CH_2, \quad (CH_3)_2CO, \quad CH_2=CH-CN, \quad C_6H_6$
(N/A) $(i)$ $CH_2=C=O$: The terminal $CH_2$ carbon is $sp^2$ hybridised,and the central $C$ is $sp$ hybridised.
$(ii)$ $CH_3-CH=CH_2$: The $CH_3$ carbon is $sp^3$ hybridised,while the $CH$ and $CH_2$ carbons are $sp^2$ hybridised.
$(iii)$ $(CH_3)_2CO$: Both $CH_3$ carbons are $sp^3$ hybridised,and the carbonyl $C=O$ carbon is $sp^2$ hybridised.
$(iv)$ $CH_2=CH-CN$: The $CH_2$ and $CH$ carbons are $sp^2$ hybridised,and the $CN$ carbon is $sp$ hybridised.
$(v)$ $C_6H_6$: All $6$ carbon atoms in the benzene ring are $sp^2$ hybridised.
$(ii)$ $CH_3-CH=CH_2$: The $CH_3$ carbon is $sp^3$ hybridised,while the $CH$ and $CH_2$ carbons are $sp^2$ hybridised.
$(iii)$ $(CH_3)_2CO$: Both $CH_3$ carbons are $sp^3$ hybridised,and the carbonyl $C=O$ carbon is $sp^2$ hybridised.
$(iv)$ $CH_2=CH-CN$: The $CH_2$ and $CH$ carbons are $sp^2$ hybridised,and the $CN$ carbon is $sp$ hybridised.
$(v)$ $C_6H_6$: All $6$ carbon atoms in the benzene ring are $sp^2$ hybridised.
