Bond line formula of HOCH(CN)2 is :

  1. [figure]
  2. [figure]
  3. [figure]
  4. [figure]

Answer

(4) [figure]

Solution

[figure]

∵ In a bond-line formula carbon atoms and the H atoms on carbon are not written; only heteroatoms (and H on them) are shown.

(A): C and its H written explicitly ⇒ (A) is not bond-line

(B), (C): CH written as text ⇒ condensed formulae, not bond-line

(D): only OH and CN shown at the ends of bonds ⇒ (D) is the bond-line formula

Answer: (4)
