Question

electrical conductivity

e (B) trigonal bipyramidal (C) octahedral (D) square planar (E) either tetrahedral or square planar 13) Which aqueous solution has the highest electrical conductivity? (A) 04 M CH3COOH (B) 0.1 M CHCICOOH (C) 0.1 M CHCI2COOH (D) 0.01 M CH3COOH (E) 0.01 M CHCI-COOH, 14) Which pair of the following aqueous solution can produce precipitates? (A) NaNO3 and H.So, 10 d H-C-Cro COOKIES

Answer 1

13)option E is correct weak electrolytes are good electrolytic conductors in dilute solution only,presence of chlorine increases acidistrength there by dissociation and electrical conductiance

3) 2NO₂ + F₂$\rightarrow$ 2NO₂F

mechanism of the rection; 1) NO₂ + F₂$\rightarrow$ NO₂F + F ( slow) ( rate determination step)

2) NO₂ + F $\rightarrow$ NO₂F (fast)

rate = K [NO₂] [F₂]

1) in step one , NO₂ reacts with F₂ to produce NO₂F and nasecent Fluorien atom

2) in step nascent atom reacts very fast with another NO₂ molecule to form NO₂F.
