$\blue{:\implies \bf{N_2H_2}}$

• This is a covalent compound. Here, the electrons are shared between hydrogen and nitrogen.

$\green{:\implies \bf{Ca(NO_3)_2}}$

• This is an ionic compound. Here, one of the element is a metal and also this compound consists of ions in it.

$\blue{:\implies\bf{CBr_4}}$

• This is a covalent compound. Here, the electrons are shared between carbon and bromine.

$\green{:\implies\bf{C_{12} H_{12}O_{11}}}$

• This is a covalent compound. Here, the electrons are shared between carbon, hydrogen and oxygen.

$\blue{:\implies\bf{SF_6}}$

• This is a covalent compound. Here, the electrons are shared between sulphur and fluorine.

$\green{:\implies\bf{H_2S}}$

• This is a covalent compound. Here, the electrons are shared between hydrogen and sulphur.

$\blue{:\implies\bf{NaCl}}$

• This is an ionic compound. Here, one of the element is a metal and also this compound consists of ions in it.

$\green{:\implies\bf{N_2H_4}}$

• This is a covalent compound. Here, both the elements are non-metals.

$\blue{:\implies\bf{CuCl_2}}$

• This is an ionic compound. Here, one of the element is a metal.

$\green{:\implies\bf{O_2}}$

• This is a covalent compound. Here, the electrons are shared between two oxygen atoms.
