Explain the following : (ix) BF3 does not hydrolyse. (x) Why does the element silicon, not form graphite-like structure whereas carbon does.

(ix) BF3 does not entirely hydrolyze. Instead, it forms boric acid and fluoroboric acid after partial hydrolysis. Because the HF is produced first, it interacts with H3BO3.

As a result, BF3 does not entirely hydrolyze.

(x); A macromolecule made up of hexagonal carbon rings is graphite.

The catenation of carbon atoms is responsible for this characteristic. The stronger the M-M bond energy and the smaller the atomic radii, the greater the likelihood to display catenation.

As you move down a group, the atomic size grows larger and the M-M bond energy decreases.

Carbon, on the other hand, exhibits catenation, but silica does not.
