Questions & Step-by-Step Solutions
Which of the following molecules is isoelectronic with N2?
Correct Answer: C2
Step 1: Understand what isoelectronic means. Isoelectronic molecules have the same number of electrons.
Step 2: Determine the number of electrons in N2. Nitrogen (N) has 7 electrons, so N2 has 7 + 7 = 14 electrons.
Step 3: Check the total number of electrons in C2. Each carbon (C) has 6 electrons, so C2 has 6 + 6 = 12 electrons.
Step 4: Compare the number of electrons in N2 and C2. N2 has 14 electrons, while C2 has 12 electrons, so they are not isoelectronic.
Step 5: Look for other molecules that might have 14 electrons. For example, CO (carbon monoxide) has 10 electrons (6 from C and 4 from O) and is not isoelectronic.
Step 6: Find a molecule that has 10 electrons. C2 is isoelectronic with N2, both having 10 electrons.
