Answer:
Spectrum 1- Biphenyl
Spectrum 2 - Benzil
Spectrum 3 - Bibenzyl
Explanation:
<u>For Benzil:
</u>
<u>
</u>The Spectrum - 2 shows this compound.The C=O and C-H bond stretching observed at following values.
<u> For Biphenyl:
</u>
<u>
</u>Spectrum - 1 shows this compound.
There are stretching vibrations from 
due to C-H stretching and C-C stretching respectively of aromatic ring only.
<u>For Bibenzyl:
</u>
Spectrum - 3 shows this compound
There are stretching vibrations at 
due to C-H stretching and C-C stretching of aromatic ring.
Along with this, stretching vibrations at 
due to C-H of alkyl.

Answer:</h3>
= 19.712 kJoules
<h3>
Explanation:</h3>
- Heat of vaporization refers to the amount of heat required to change a unit mass of a substance from liquid to gaseous state without change in temperature.
To calculate the amount of heat, we use,
Amount of heat = Mass × Heat of vaporization
Q = m×Lv
Given;
Mass of liquid Zinc = 11.2 g
Lv of liquid Zinc = 1.76 kJ/g
Therefore;
Q = 11.2 g × 1.76 kJ/g
= 19.712 kJ
Thus, the amount of heat needed to boil 11.2 g of zinc is 19.712 kilo-joules.
