how many electrons do two ethylene monomers (c₂h₄) share to form a covalent bond?\n1\n2\n3\n4
Answer
Explanation:
Step1: Recall covalent - bond electron - sharing rule
In a covalent bond, each bond is formed by the sharing of a pair of electrons.
Step2: Analyze ethylene structure
Ethylene ($C_2H_4$) has a carbon - carbon double bond. A double bond consists of one sigma bond and one pi bond, and in total, 4 electrons are shared between the two carbon atoms. When two ethylene monomers interact to form a covalent bond (for example, in polymerization), the most common covalent bond formed is a single bond which involves the sharing of 2 electrons.
