Question

Write the general electronic configuration of 4d series. Explain haloform reaction.​

Answer 1

Answer:

The general electronic configuration of 4d series is 5s1 to2 4d 1 to 10. The differentiating element enters into 4d orbital.

Answer 2

The general electronic configuration of the 4d series is $[Kr]5s^{1-2}4d^{1-10}$.

• The 4d transition elements exist from Y to La.
• These elements have progressively filled 4d and 5s orbital.
• The general electronic configuration is $[Kr]5s^{1-2}4d^{1-10}$.

Haloform is a type of halogenation reaction of the ketone.

• In a haloform reaction, a methyl ketone undergoes a halogenation reaction in presence of a base.
• The reaction is as follows-
• $Ph-CO-CH_3+Cl_2\rightarrow Ph-CO-CH_2Cl$.
• As in the above reaction, a phenyl methyl ketone reacts with chlorine to form phenyl chloromethyl ketone.
