Dichloromethan (DCM) hay methylen chloride (MC) là một hợp chất hóa học với công thức CH 2Cl 2 Đây là một chất lỏng không màu, dễ bay hơi với mùi thơm nhẹ. Nó được sử dụng rộng rãi làm dung môi, vì là một trong những chlorcarbon ít độc nhất, và nó có thể trộn lẫn với hầu hết các dung môi hữu cơ. WebFurther experiments showed that 3º-hydrogens are about 5 times more toward halogen atoms 1º-hydrogens. Thus, light-induced chlorination of 2-methylpropane gave predominantly (65%) 2-chloro-2-methylpropane, the substitution product of the sole 3º-hydrogen, despite the presence of nine 1º-hydrogens in the molecule.
