Question

In a molecule of methane, carbon (having four valence electrons) binds to four hydrogen atoms. How many lone pairs of electrons will be represented in the Lewis structure of methane? A. four B. two C. one D. zero

Answer 1

Answer: option D, zero

Step-by-step explanation:

Since methane formula,CH4

And Carbon has atomic number-6 and has 4 electrons in outer shell. These 4 electrons will combine with 1s1 electron of each 4 Hydrogen results zero unpaired electrons.

Hence D is correct answer.

Answer 2

The valence electrons of the carbon atom is equal to 4 and each of the hydrogen has 1 valence electron. In the Lewis structure, each of the valence electron of carbon and those of the hydrogen will be shared. Thus, the answer is letter "D. zero".
