Question

Four covalent bonds are formed by an element in its compounds and that element is:

• A. Na
• B. Ca
• C. C
• D. F
• E. Li

Answer 1

The correct option is C C

Four covalent bonds are formed by an element in its compounds and that element is C.
For example, in methane, $C{H}_4$ , C forms four covalent $C-H$ bonds.
Similarly, in carbon tetrachloride, $CC{l}_4$ , C forms four covalent $C-Cl$ bonds.
All other elements given in the options form ionic bonds as they are either highly electropositive or highly electronegative elements.
