Răspuns:
a
CH3-CH2-CHCl-CH3 ----> CH3-CH=-CH-CH3 + HCl ( in prezenta de solutie alcoolica de baza tare)
b
c,m= n/V---> n=0,1x2mol=0,2mol
din ecuatia chimica, se deduce n= 0,2mol 2-CLOROBUTAN
M,C4H9Cl=92,5g/mol
m=nxM= 0,2X92,5g=18,5g 2-clorobutan pur
p=18,5x100/80g==m,i=m,px100/p--->
m,i= 18,5x100/80g=23,125g 2clorobutan impur
