benzoic acid melting point

Why is benzoic acid stronger than acetic acid but weaker

Acidity of carboxylic acid depends on the type of substituent attached to it An electron withdrawing group increases the acidity while an electron donating group decreases the acidity The carboxylate ion obtained due to loss of proton should be

The Recrystallization of Benzoic Acid

PROCEDURE: 1) Set a small amount of the impure benzoic acid aside and keep it until next week You will compare the melting point of this impure sample to the benzoic acid recovered from recrystallization 2) Weigh the impure benzoic acid crystals obtained last week using the analytical balance and place them in a 250 mL Erlenmeyer flask

Benzoic Acid

Benzoic acid (p K a 420) is a slightly stronger acid than acetic acid (pK a 476) This must be largely attributed to the greater electronegativity of thesp 2-hybridised ring carbon atom since acrylic acid (CH 2 = CHCO 2 H pK a 425) has a comparable acidity The effect of meta-or para-substituents on the acidity of substituted acids (see Table 3) may be rationalised in terms of the

Recrystallisation of benzoic acid and determination of its

The melting point range of an impure substance is lower and broader than that recorded for a pure sample of the same substance Comparing the melting point ranges of the benzoic acid sample before and after recrystallisation with the melting point range of pure (Analar) benzoic acid will therefore indicate the success of the recrystallisation
