which of the lewis structures in the image is correct? a b c d
which of the lewis structures in the image is correct? a b c d
Answer
Brief Explanations:
- For Lewis structures, hydrogen forms one bond. Carbon forms four bonds. Nitrogen forms three bonds and has one lone pair (two dots).
- In option A: Carbon has only three bonds (two with H and one single dot which is incorrect as it should have four bonds).
- In option B: Hydrogen is shown with a dot (incorrect as H has one electron which is already in the bond with C. Also, carbon has incorrect bonding count.
- In option C: Nitrogen has only two bonds (incorrect as N should have three bonds).
- In option D: Nitrogen has three bonds (with three H atoms) and one lone pair (two dots), which is correct as per Lewis structure rules.
Answer:
D.
