`K_(a)` increases in benzoic acid substituet X bonded at pare position then X is :

pK_(a) increases in benzoic acid when substituent "x" is bonded at para - position, then "x" is-

pK_(a) increases in benzoic acid when substituent ''x'' is bonded at para-position, then ''x''is

pK_(a) increases in benzoic acid when substituent ''x'' is bonded at para-position, then ''x''is

Electrophilic substitution in benzoic acid takes place at meta position why ?

An increase in the charge of the positive ions that occupy lattice positions brings in a/an…… in methallic bonding.

Give reasons: Electrophilic substitution in benzoic acids takes place at meta position.

Assertion: Ortho substituted benzoic acids are stronger than benzoic acid. Reason: Ortho substituted tends to prevent coplanartity of -COOH with ring. Thus resonance is diminished which increases acidic strength (ortho effects)

29,Roots of 2x^(2)-x+k=0 are positive then k is

12.2 g of benzoic acid is dissolved in (i) 1 kg acetone (K_(b) = 1.9 K kg mol^(-1)) and (ii) 1 kg benzene (K_(b) = 2.6 K kg mol^(-1) . The elevation of boiling points are 0.19^(@)C and 0.13^(@) C , respectively. a. What are the molar masses of benzoic acid in the two solutions ? , b. What are the structures of benzoic acid in the two solutions ?
