The origin of acidity and basicity in organic compound is great interest and provides an extensive comparison. Among hydrocarbons `%` a character is taken in aC Count while to decide the acidity, in simple aliphatic acids, more the number of alkyl groups, (+1 effect) less is the acidity `&` more the (-1 effect) groups larger the acidity and vice-versa in the case of simple alphatic bases. Benzoic acid is more stronger than carboxylic acid as benzoate ion is stablised more by resonance. Aromatic amines are less basic than apiphatic amine as the electron pair is less available in case of aromatic amines. The presence of solvent also plays a very important role and at time governs the order too.

A.
B.
C.
D.
