Question: Determine the pH of a 0.28 M {eq}CH_3NH_3I {/eq} solution. Acidic Ionic Compound: An amine is an uncharged organic compound that contains a functional group with the generic formula {eq}\rm NR_3 {/eq}. This functional group acts as a Bronsted-Lowry base to deprotonate wa...
we observed the relatively weak two main absorption peaks at 0.95 and 1.87 THz. The measured absorption spectrum is analyzed by density-functional theory calculations. The modes at 0.95 and 1.87 THz are assigned to the Pb-I vibrations of the inorganic components in the tetragonal phase. ...

官能团(Functional Group)是指有机分子中赋予化合物特定化学性质的一类原子或原子团。它通常由特定的原子或键的排列构成,是决定化合物化学反应活性和物理性质的核心结构单元。官能团可以显著影响分子的极性、酸碱性、溶解性、沸点、熔点及其他化学或物理特性 [1]。 常见的官能团包括:羟基(-OH)、羧基(-COOH)、醛基(-...
