丙基

Propyl

在有机化学中,丙基是具有化学式-​​C 3 H 7的直链三碳烷基取代基。 通过除去连接到丙烷的末端碳上的一个氢原子获得的取代基形式。 丙基取代基通常在有机化学中以符号Pr表示。 通过除去附着在丙烷的中间碳上的氢离子,可以得到异丙基形式的1-甲基乙基或异丙基。 线性丙基有时称为正常,并用前缀n写成。 然而,n-是多余的,因为没有任何前缀意味着无支链的丙基。 此外,还有一种称为环丙基或环丙基的第三个环状。 它不是具有化学式为-C 3 H 5的其它两种形式的异构体。 In organic chemistry, propyl is a linear three-carbon alkyl substituent with chemical formula -C3H7. It is the substituent form obtained by removing one hydrogen atom attached to the terminal carbon of propane. A propyl substituent is often represented in organic chemistry with the symbol Pr. There is an isomeric form of propyl named 1-methylethyl or isopropyl obtained by removing a hydrogen ion attached to the middle carbon of propane. Linear propyl is sometimes termed normal and written with a prefix n-. However, n- is redundant because the absence of any prefix implies an unbranched propyl. In addition there is a third, cyclic, form called cyclopropyl, or c-propyl. It is not isomeric with the other two forms, having the chemical formula -C3H5.
