Answer:
Step-by-step explanation:
C₄H₈ = Alkene because it contains one double bond
General formula of alkene is CnH2n .
CH₃CH₂CH₂CH₂CH₂NH₂ = Amine ( primary )
name is pentyl amine .
The third one is benzene which is aromatic in nature .
CH₃CH₂COOCH₂CH₂NH₂ .
It is an ester as follows
CH₃CH₂COCl + NH₂CH₂CH₂OH = CH₃CH₂COOCH₂CH₂NH₂
acid chloride + alcohol = ester + water .
