Chlorobutane
The chlorobutanes (also: butyl chlorides ) are among the organic chemical substances and form a group of four structurally isomeric saturated chloroalkanes with four carbon atoms. They have the general empirical formula C 4 H 9 Cl and a molar mass of 92.57 g / mol. The sec -butyl chloride is also chiral and occurs in two enantiomeric forms. So there are a total of five isomeric chlorobutanes.
