Question

Compound (A) has a molecular formula C6H13Br. When it is heated with magnesium metal in ether, a Grignard reagent is formed which on hydrolysis with dil.acid produces the compound n-hexane as a product . When compound (A) is reacted with sodium metal in ether . the product obtained is 4,5-diethyl octane.....From above information deduce the structural formula of (A)...

Answer 1

CH3-CH2-CH2-CH-CH-CH2-CH2-CH3
..............................I......I
........................C2H5..C2H5

This compound could be produced from:

...........CH3-CH2-CH2-CH-Br& + 2 Na = 2NaBr + A
2.......................................I
.....................................C2H5


Your compound is :
CH3-CH2-CH2-CH-Br &
..............................I
............................C2H5
