WebThe simplest alkanes are methane (\ce {CH_4}), (CHX 4), ethane (\ce {C_2H_6}), (CX 2HX 6), and propane (\ce {C_3H_8}). (CX 3HX 8). The alkanes are also called as paraffins. In an alkane, all 4 4 valencies of the carbon … WebTerminal alkynes, like acetylene itself, are mildly acidic, with p Ka values of around 25. They are far more acidic than alkenes and alkanes, which have p Ka values of around 40 and 50, respectively. The acidic hydrogen on terminal alkynes can be replaced by a variety of groups resulting in halo-, silyl-, and alkoxoalkynes. shanys parisWebProtonation of the alkene to generate the more stable carbocation. The pi electrons act as a Lewis base. Step 2: Attack of the nucleophilic water molecule on the electrophilic carbocation creates an oxonium ion. Step 3: An acid / base reaction.
