Among the species : \(C{O_2},C{H_3}CO{O^ - },\) \(CO,C{O_3}^{2 - },\) \(HCHO\) which has the weakest carbon- oxygen bond
1 \(C{O_2}\)
2 \(C{H_3}CO{O^ - }\)
3 \(CO\)
4 \(C{O_3}^{2 - }\)
Explanation:
(d) Among the given species. The bond dissociation energy of \(C - O\) bond is minimum in case of \(CO_3^{2 - }\) by which \(C - O\) bond become more weaker in \(CO_3^{2 - }\) or the bond order of \(CO_3^{2 - }\) \((1.33)\) is minimum so the bond become weaker.

Valency of sulphur in \(N{a_2}{S_2}{O_3}\) is
1 \(2\)
2 \(3\)
3 \(4\)
4 \(6\)
Explanation:
(a) Valency of \(N{a_2}{S_2}{O_3}\) is supposed to be \(x,\) then \(2 + 2x + ( - \,6) = 0\), \(2x - 4 = 0\), \(x = 2\).

The following salt shows maximum covalent character
1 \(AlC{l_3}\)
2 \(MgC{l_2}\)
3 \(CsCl\)
4 \(LaC{l_3}\)
Explanation:
(a) Among the given choice \(Al\) is least electropositive therefore, the bond between \(Al\) and \(Cl\) will be least ionic or most covalent or the difference in electronegativeity of two atom is less than \(1.8.\)
Chemical Bonding and Molecular Structure

Which type of bond is present in \({H_2}S\) molecule
1 Ionic bond
2 Covalent bond
3 Co-ordinate
4 All of three
Explanation:
(b)Electronic configuration of \(_{16}{S^{32}} = 1{s^2},2{s^2},2{p^6},3{s^2},3{p^4}\). In the last orbit it has only \(6\) electron. So it require \(2\) electron to complete its octet, therefore it share \(2\) electron with two hydrogen atom and forms \(2\) covalent bond with it.
