The element E is carbon.
●element E forms hallide with formula EH4 .since valency of hallide is one as it requires only 1 electron to complete its noble gas configuration.
●By criss cross formula becomes EH4 so valency of element should be 4 as element with valency 4 is carbon with electronic configuration is 2,2 hence element is E is carbon .
●eg)CH4 where H is hallide cl ,F ,Br etc so formula is CCl4.
Element E is carbon CCl4 has low boiling point .
