If one of the 'H' atom of NH3 is replace by R = alkyl group, they are referred as primary amine. If two 'H' atoms of NH3 are replace by same or different alkyl group, they are referred as secondary amine. If all the three 'H' atom of NH3 are replace by same or different alkyl group, they are referred as tertiary amine.
In present case, option C has 2 'H' atoms of NH3 replaced by alkyl group. Hence it is secondary amine.
Lithium fluoride is the compound name
