4(109) CN - is a strong ligand because :
(A) It is a pseudo halide
(B) It carries negative charge
(C) It forms high spin complexes with metal species
(D) It accepts electrons from metal species
4113) Which of the following is least reactive towards nucleophilic substitution
(A) (CH3)3 = C - cl
(B) CH2 = CH - cl
(C) CH3CH2cl
(D) CH2 = CH CH2 cl
2149 a)
frequency remains const...... velocity will vary, so wavelength will vary
21already reasoned...
113 b)........ the cation formed, vinylic cation , will be least stable.
21109 c ... CN- is a strong ligand ... so it forms high spin complexes with metal species
4Where is the reason
u just said this " frequency remains const...... velocity will vary, so wavelength will vary "
Y does frequency remain constant ??
Dont the no of oscillations change ??
4U r 109 answer is wrong
113 r8
btw ur answer statements r same as the statements given in the Page test solutions
I posted here only becoz they were not satisfying
and again u re giving me the same reasons :O
