carbene

the carbon which has lone pairs has already made 2 bonds. Hence there is no need for any extra H. If you are drawing a carbene, then the image is correct

Isn't it necessary that for a carbene both the bonds shld. be with hydrogen and none else??

no.. this is also a carbene :CCl₂ all that is required for a carbene is a lone pair

Asish is correct...infact there are carbene-like intermediates also, such as nitrenes.
