Which statement describes the particles of an ideal gas according to the kinetic molecular theory? (1) the gas particles are arranged in a regular geometric pattern.
(2) the gas particles are in random, constant, straight-line motion.(3) the gas particles are separated by very small distances, relative to their sizes.(4) the gas particles are strongly attracted to each other.

Benzonitrile (c6h5cn) is reduced to two different products depending on the reducing agent used. treatment with lithium aluminum hydride followed by water forms k, which has a molecular ion in its mass spectrum at 107 and the following ir absorptions: 3373, 3290, 3062, 2920, and 1600 cm-1. treatment with a milder reducing agent forms l, which has a molecular ion in its mass spectrum at 106 and the following ir absorptions: 3086, 2850, 2820, 2736, 1703, and 1600 cm-1. l shows fragments in its mass spectrum at m/z = 105 and 77. propose structures for k and l and choose an explanation for how this could be concluded.
