Question

Tag all the sp³ hybridized carbon atoms in this molecule. If there are none, please check the box below.

C C C H H H H

There are none.

Answer 1

C3H4 may be written as

1)CH2=C=CH2 Allene

In allene, central carbon - - - SP

Terminal Carbons - - - - - SP2

no SP3 Hybridisation in this structure.

2) Cyclo propene : - - - SP2

3)Propyne CH=_C-CH3

In prooyne 1,2 carbons - - - SP

3rd Carbon is SP3 Hybridised.

So, the SP3 Hybridization is seen in Propyne.
