Bond line formula of HOCH ( CN ) 2 is:

A bond line structural formula is another method of structural representation of organic compounds. Here, every bond is represented as a line in a zigzag manner.  The carbon and hydrogen atoms are not written and do not appear in the structure. Only, the bonds present between the carbon atoms are shown.

In the bond-line formula for $\mathrm{HOCH}{\left(\mathrm{CN}\right)}_2$  is
