Question

T. Y.B.Sc. (II) Organic Chemistry
The carbonyl group (>C=O) frequency of phenyl acetic acid is lower than methy
benzoate due to -
(a) presence of -COOH group in phenyl acetic acid
(b)-I effect of phenyl ring attached to carbonyl carbon in methyl acetate.
(c)-I effect of phenyl ring attached to carbonyl carbon in phenyl acetic acid.
(d) None of these
:) The compound C H2O do not show any absorption band above 1500 cm-due to -
(a) presence of one c=c bond.
(b) presence of all o-bonds
(c) presence of c=o bond.
(d) None of these.
1-butyne shows two distinct absorption peaks in I.R. spectra but 2–butyne does not.
(a) 1-butyne is symmetrical while 2-butyne is unsymmetrical
(b)2-butyne is symmetrical while 1-butyne is unsymmetrical
(c) they have different molecular formula
(d) None of these
frequency than cyclobutanone because​
