Covalent compounds are generally ...... in water
1 Soluble
2 Insoluble
3 Dissociated
4 Hydrolysed
Explanation:
(b) Water is a polar solvent while covalent compounds are non-polar so they usually insoluble in water.
Chemical Bonding and Molecular Structure
11917
Which one is the electron deficient compound
1 \(ICl\)
2 \(N{H_3}\)
3 \(BC{l_3}\)
4 \(PC{l_3}\)
Explanation:
(c) \(BC{l_3}\) is electron deficient compound because it has only \('6’\) electrons after forming bond.
Chemical Bonding and Molecular Structure
11918
Which among the following elements has the tendency to form covalent compounds
1 \(Ba\)
2 \(Be\)
3 \(Mg\)
4 \(Ca\)
Explanation:
(b) Due to its small size and \(2\) electrons in \(s-\)orbital \(Be\) forms covalent compound.
Chemical Bonding and Molecular Structure
11919
Silicon has \(4\) electrons in the outermost orbit. In forming the bonds
1 It gains electrons
2 It loses electrons
3 It shares electrons
4 None of these
Explanation:
To complete an octet, silicon requires \(4\) more electrons. So, in bonding, it shares its electrons. Removing \(4\) electrons from silicon is difficult.
