The number of dative bonds in sulphuric acid molecules is
1 \(2\)
2 \(1\)
3 \(0\)
4 \(4\)
Explanation:
Dative bonds are formed by donation of a pair of electrons to the central atom. In sulphuric acid sulphur forms only covalent bond. There is no dative (coordinate) bond in sulphuric acid.

Which of the following compounds has coordinate (dative) bond
1 \(C{H_3}NC\)
2 \(C{H_3}OH\)
3 \(C{H_3}Cl\)
4 \(N{H_3}\)
Explanation:
(a) \(C{H_3}N\vec = C\) contain dative bond.

What is the nature of the bond between \(B\) and \(O\) in \({({C_2}{H_5})_2}OB{H_3}\)
1 Covalent
2 Co-ordinate covalent
3 Ionic bond
4 Banana shaped bond
Explanation:
\(As BH _3\) is a lewis acid, it can accept a lone pair of electron donated by alkoxy group hence the bond formed is co-ordinate covalent bond. \(\left( C _2 H _5\right)_2 O\) gives one lone pair of an electron to \(BH _3\). So, it is called the electron-pair donor.

1 Covalent
2 Co-ordinate covalent
3 Ionic bond
4 Banana shaped bond
Explanation:
\(As BH _3\) is a lewis acid, it can accept a lone pair of electron donated by alkoxy group hence the bond formed is co-ordinate covalent bond. \(\left( C _2 H _5\right)_2 O\) gives one lone pair of an electron to \(BH _3\). So, it is called the electron-pair donor.
