True or false.
(a) Gringnard reaction of an ester gives tertiary
alcohol.

Mid-Term,Spring 2019 Organic Chemistry Lab I1- CHML 242-03 (10pts) Q12. True or False (a) Grignard reaction of an ester gives tertiary alcohol (b) IR frequency gives the information about presence of different types of bonds in a molecule (c) NMR can predict total number of proton and carbon in a molecule. (d) Diels-Alder reaction is possible between two dienophiles or two dienes. (e) Nitration is a nucleophilic substitution reaction. (0 Grignard reaction with COo: gives acid. (8) Benzene shows one peak in ‘H-NMR proton and six peaks in 1″C-NMR (h) IR frequency for C-О is 1700 cm’l () Nitration reaction needs HNOs and H:0 (G) A six membered ring can be obtained by Diels-Alder reaction
