Concept explainers
Interpretation:
The three-dimensional formula for androsterone and norethynodrel is to be given.
Concept Introduction:
>Androsterone, a secondary male sex hormone, is an endogenous steroid hormone. It is a weak androgen with a molecular formula of
The structure of androsterone consists of four rings, three six membered carbon rings and one five membered carbon ring. It consists of a hydroxyl group at the third carbon atom, two methyl groups at the tenth and the thirteenth carbon positions respectively, and a
Norethynodrel is a group of synthetic steroids having functions similar to those of progesterone. These are widely used as oral contraceptives; however, now have been discontinued. Its molecular formula is
The structure of norethynodrel consists of three six membered carbon ring and one five membered carbon ring. It consists of a hydroxyl group at the third carbon atom, two methyl groups at the tenth and the thirteenth carbon positions respectively, and a ketone group at the seventeenth carbon position.

Nitration of the isomers at all possible positions was once used to determine their structures. The isomer that melts at 210 °C gives two mononitro isomers. The isomer that melts at 343 °C gives three mononitro isomers. The isomer that melts at 427 °C gives only one mononitro isomer. Show which isomer has which melting point.arrow_forward
- Give simple tests to distinguish the following pairs of compounds :(i) Ethanal and Propanal(ii) Benzaldehyde and Acetophenone(iii) Benzoic acid and Ethyl benzoatearrow_forwardGive 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_forwardWrite a structural formula for each of the following compounds: (a) m-Chlorobenzoyl chloride (b) Trifluoroacetic anhydride (c) cis-1,2-Cyclopropanedicarboxylic anhydride (d) Ethyl cycloheptanecarboxylate (e) 1-Phenylethyl acetate (f) 2-Phenylethyl acetate (g) p-Ethylbenzamide (h) N-Ethylbenzamide (i) 2-Methylhexanenitrilearrow_forward
