Question

In a certain organic compound, one of the carbon atoms is bonded to three atoms. One of these is a carbon atom and the other two are hydrogen atoms. What type of bond exists between the two carbon atoms?

Double Covalent

Ionic

Ion Dipole

Answer 1

The answer is double covalent.

Answer 2

Since the C is bonded to 2 H atoms,

it needs two more bonds to complete the octet of C(as C forms four bonds in total),hence C-C bond is double covalent bond

The bonded C atom is shown as bold C here:

-C=CH2

The  bond between the two C atoms is Double Covalent.
