Explain the following :  (a) Highly branched acids such as are less acidic than unbranched acids.  (b) `K_(a_1)` for maleic acid is greater than that for fumaric acid or `pK_(a_1)` for maleic acid is less than that for fumaric acid.  ( c) `K_(a_2)` for fumaric acid is greater than that for maleic acid or `pK_(a_2)` for fumaric acid is less than that for maleic acid.  (d) Phthalic acid is a stronger acid than either isophthalic or terephthalic acids but phthalate monoanion is weaker than isophthalate and terephthalate monoanions.  ( e) `o-`Nitro benzoic acid `(pK_a = 2.21)` is stronger acid than `3,5-`dinitrobenzoic acid `(pK_a = 2.80)` but weaker than `2,4-`dinitro benzene acid in water.
