Question

QUESTION 1 Which of the following species cannot act as a Lewis acid? 2. BF3 b. Ag* NH4 e. BeCl2

Answer 1

Lewis acid The species which can accept a lone part of elecbon is called as lewis acid.. It is the atom od molecule having incompletely Filled outermost orbital. It has tendency to accept an electron pair from base, Answer: 44 NH4 Species do not acts as low is acid because nitrogen atom in Ang is not able to accept election Dair. Its outer elecbonic configuration is hasr Hilled exactly so it has no tendency to form one another bond. Biz is lewis acid 58: 15, 25 ap! G. Por B: Is, 25 ap G.S. 11111T GS is, 25, 2p2 E.S. • In excited state elecbonic confr of B it has 3 unpaired electron. These 3 elecbon can korm bond I with 3 fluorine arom. But still one orbital is left empty so This atom have tendoncy to accept an electron pair from bave, so it is lewis acid. Ago Electronic confr. 15, 25%, apo , 35², 3p8, 45², 3do , 4pf 5s, 42 47 [kg] 58°, 4010 Its 5s orbital is empty, so it has tendency to I accept an elecbon pair. Therefore it is lewis acid.

Page Hydrogen atom has elecbonic configuration is in ground state & in H is orbital is empty so this asom have tendency to accept electron pair. Therefore it is lewis acid Becho Be : 15 , 25, apº 15,25", zp' E.S. This molecule can form two bonds still outer orbity is empty so it is also lows acid. HH4 ion does not accept a lone pair. It reach with base leaving with as a gas. NH4 + on H4 the .

Answer 2

Yes, I completly agree that the options of the answer truely show the pure nature of chemistry in its fullest form. Is it a Lewis Acid? what is a Lewis Acid? what even is a acid? Who is Lewis?

Answer 3

The NH4 cannot react with lewis acid

Answer 4

The NH4 cannot react with lewis acid
