Concept introduction:
舧 A carbohydrate is a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen-oxygen atom ratio of 2:1
舧
舧 Carbohydrates are oxidized by
舧 Aldaric acids are carbohydrates having two
舧
舧 Aldaric acids (obtained from oxidation of aldohexoses) produces lactones of the same order that is as:
舧 The reaction in which there is removal of water molecule is called dehydration reaction.

- Give reasons: (i) Bond length of C = O in carboxylic acids is slightly larger than C = O bond length in carbonyl compounds. (ii) There are two –NH2 groups in semicarbazide. However, only one –NH2 group is involved in the formation of semicarbazones. (iii) Benzoic acid is less soluble in water than acetic acid. (iv) Formic acid is a stronger acid than acetic acid.arrow_forwardGive the chemical tests to distinguish between following pair of compounds : (i) Propanol and propanone (ii) Ethyl acetate and methyl acetate (iii) Benzaldehyde and benzoic acid (iv) Benzaldehyde and acetaldehyde (v) Formic acid and acetic acid (vi) Propanal and propanol (vii) Ethanoic acid and ethylethanoatearrow_forward1.
