Answer 1

2- the covalent molecules are formed when the metals or molecules involved share the electrons instead of donating or accepting the electron, thus covalet molecule is formed by the molecules which have very low electronegativity and are formed by sharing of electrons

answer- option c- covalent bond

other options are incorrect becuase in case of all the sharing of electron donot occur.ionic bonds are formed when the electron is removed or accepted similarly with functional groups, they give atoms or specific molecule for the characteristic reaction, in covalent bond , sharing of the electrons occur

3- answer c- methyl group

Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out. except methyl group, one can see every group contain atoms which have appreciable electronegativity difference which makes them polar compounds whereas in methyl the carbon and hydrogen donot have much difference thus is considered as non polar molecule

4- answer b- hydroxyl group

The substituent -NH₂ is called an amino group.

-OH is called hydroxyl group

C=O is carbonyl group
