a) Organic compounds are those compounds which have carbon atoms directly bonded to hydrogen atoms along with other atoms. They mainly have covalent bonding.
The bond which is formed by equal sharing of electrons from both the participating atoms. The pair of electron participating in this type of bond is called bonding pair.
Now,
There are many elements which combine with carbon in organic compounds. The compounds are as follow:
Chlorine
Nitrogen
Oxygen
Hydrogen
Bromine
Sulphur
Heteroatoms are atoms other than carbon and hydrogen in organic compounds. Out of the above listed elements all except hydrogen are heteroatoms.
Hence,
Number of heteroatoms are:
Chlorine
Nitrogen
Oxygen
Bromine
Sulphur
c) Electronegativity is an atom's ability to attract the shared pair of electrons towards itself. If the electronegativity difference is less, the electrons are shared and if it is more, the electrons are transferred. When we go left to right in a period, electronegativity of elements increases while going down a group, electronegativity decreases.
All the atom listed above, except hydrogen and sulphur have more electronegativity as compared to carbon.
In case of sulphur, carbon is more electronegative than sulphur. This is so because carbon lies in second period while sulphur lies in third period.
In case of hydrogen, carbon is more electronegative than hydrogen.
Thus from the above conclusion we can say that, all elements listed above except hydrogen and sulphur have more electronegativity as compared to carbon.
