Number of compounds with one lone pair of electrons on central atom amongst following is _ O 3 , H 2 O , SF 4 , ClF 3 , NH 3 , BrF 5 , XeF 4

Step-by-step solution

A pair of electrons which is not shared by any of the reacting atoms is called a lone pair of electrons. Lone pairs are found in the outermost electron shell of atoms. They can be identified by using a Lewis structure. The structures of the compounds are as follows, Hence the compounds NH 3 , O 3 , SF 4 and BrF 5 have one lone pair on central metal atom.
