CHEMISTRY CHEMICAL BONDING QUIZ-1
Dear Readers,
The one subject in NEET which is candidates who can easily attain good marks is Chemistry. That's the reason, often, one doesn’t pay notice and choose to compromise it. But if one wants to rank above others, the tip is to be thorough with NEET chemistry concepts. The understanding of reactions and definite basic understanding is what requires major attention in Chemistry but once done it only gets simpler from there. The main focus on the to-do list should be on getting a hang of the NCERT syllabus of NEET chemistry..
Q1. Debye an unit of dipole moment is of the order of:
Solution
1debye=10-18 esu.
1debye=10-18 esu.
Q2.The d-orbital involed in sp3 d hybridization is
Q3. In OF2, number of bond pair and lone pairs of electrons are respectively:
Q4. The d – orbital involved in sp3d – hybridisation is
Solution
The d-orbital involved in sp3d -hybridization is d_zx.
The d-orbital involved in sp3d -hybridization is d_zx.
Q5.
Solution
Valencies of L,Q,P and R is-2,-1,+1, and +2 respectively. So, they will form P2L,RL PQ, and RQ2
Valencies of L,Q,P and R is-2,-1,+1, and +2 respectively. So, they will form P2L,RL PQ, and RQ2
