Question

Which of the following will not show geometrical isomerism?

• A. $\lbrack Co(NH_{3})_{4}Cl_{2}\rbrack$
• B. $\lbrack Co(e)_{2}Cl_{2}\rbrack Cl$
• C. $\lbrack Co(NH_{3})NO_{2}\rbrack Cl_{2}$
• D. $\lbrack Pt(NH_{3})_{2}Cl_{2}\rbrack$

Answer 1

Answer: (C)

$\lbrack Co(NH_{3})NO_{2}\rbrack Cl_{2}$

Answer 2
