Amul India Interview Questions and Answers

NMR values of aromatic rings are affected by electron withdrawing and donating groups.

• Electron withdrawing groups shift NMR values downfield (to higher ppm)

• Electron donating groups shift NMR values upfield (to lower ppm)

• Examples: Nitro group (downfield shift), Methoxy group (upfield shift)

Protection and deprotection of organic compounds involves temporarily modifying functional groups to prevent unwanted reactions.

• Protection involves adding a protecting group to mask a reactive functional group

• Deprotection involves removing the protecting group to reveal the original functional group

• Common protecting groups include Boc (tert-butyloxycarbonyl) and TBDMS (tert-butyldimethylsilyl)

• Examples: Boc protection of an amine group, TBDMS protection of a hydroxyl group

NMR and IR values are analytical techniques used to determine the structure of a compound.

• NMR (Nuclear Magnetic Resonance) spectroscopy provides information about the number and types of atoms in a molecule, as well as their connectivity.

• IR (Infrared) spectroscopy is used to identify functional groups present in a compound based on the absorption of infrared radiation.

• NMR values are reported in ppm (parts per million) and can indicate the chemical environment of different nuc...read more

Benzene can be converted to chlorobenzene through electrophilic aromatic substitution using chlorine gas and a catalyst.

• Use chlorine gas and a catalyst in the presence of benzene

• Electrophilic aromatic substitution mechanism is followed

• Chlorobenzene is formed as the final product
