CHE SIGNIFICA METHYL IN INGLESE
Gruppo di metile
Un gruppo metilico è un alchile derivato da metano, contenente un atomo di carbonio legato a tre atomi di idrogeno - CH3. Il gruppo è spesso abbreviato Me. Tali gruppi di idrocarburi si verificano in molti composti organici. È un gruppo molto stabile nella maggior parte delle molecole. Mentre il gruppo metilico è di solito parte di una molecola più grande, si può trovare da sola in una delle tre forme: anioni, cationi o radicali. L'anione ha otto elettroni di valenza, i radicali sette e il cationo sei. Tutte e tre le forme sono altamente reattive e raramente osservate.
definizione di methyl nel dizionario inglese
La definizione di metile nel dizionario è costituita da, o contenente il gruppo monovalente di atomi CH3. L'altra definizione di metile è un composto organometallico in cui i gruppi metilici sono legati direttamente a un atomo di metallo.
