Solution:
QUESTION: 16

Which of the following is a Lewis acid?

Solution:

"Lewis Acid is something that accepts a pair of electrons."

"A Lewis Base is something that donates a pair of electrons."

So Cl- would be a Lewis base.

NH3 is a Lewis Base.

BF3 is NOT a Lewis Base because it has an empty p orbital, this is a Lewis Acid.

C2H5OH is ethanol and that is a Lewis Base because the Oxygen has two lone pairs of electrons that it can donate.

Solution:
QUESTION: 28

The frequancy factor in the collision theory is__

Solution: Frequency factor in collision theory is directly proportional to √T because,as temperature increases, molecules move faster; as molecules move faster, they are more likely to collide and therefore affect the collision frequency
QUESTION: 29

Among the following metal carbonyls, the C --- O bond order is lowest in :

Solution:

Mn+ = 3d54s1 in presence of CO effective configuration = 3d64s0.
Three lone pair for back bonding with vacant orbital of C in CO. So, it has maximum bond order..

Fe0 = 3d64s2 in presence of CO effective configuration = 3d8 four lone pair for back bonding with CO.

Cr0 = 3d54s1
Effective configuration = 3d6. Three lone pair for back bonding with CO.

V− = 3d44s2 effective configuration = 3d6three lone pair for back bonding with CO.

Maximum back bonding is present in Fe(CO)5 therefore CO bond order is lowest here.
