Q3. NMR values of aromatic ring and affects on them from electron withdrawing abd donating groups
Ans. 
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)

Q5. Nmr and ir values for given compound
Ans. 
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) ...read more
