Answer 1

The datas given for mass/mL is doubtful. NaBH4 is a solid compound and the data is given in mL which is not possible.

Giving the mmol according to the data

Cyclohexanone = 194/98.15=1.97 mmol

Cyclohexanol = 4017/100.16= 40.1 mmol.

Data is given wrong as the cyclohexanol formed is much more than the starting material and hence more than 100%

IR peaks

Broad peak at 3354 is for O-H stretching frequency

Sharp peak at 2932 is for C(Sp^{​​​​​3})-H stretching frequency

Sharp peak at 1060 is for C-O stretching frequency.
