CH3-CH2-CH=CH2 has hybridisation: — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Write down the structure of 1-butene: CH3-CH2-CH=CH2. Step 2: Identify the hybridization of each carbon from left to right: the methyl carbon (CH3) and methylene carbon (CH2) form only single bonds (sp3). The two vinylic carbons (CH=CH2) form a double bond (sp2). Step 3: Thus, the hybridization of the carbon atoms is sp3, sp3, sp2, sp2.
