Nonpolar molecule?

Question

Which formula represents a nonpolar molecule?

H2S

HCI

CH4

or NH3

Answer 1

CH4

Answer 2

Polar molecule have:
1) Linear Molecules (such as CO)
2) Molecules with a single H (such as HCl)
3) Molecules with an OH at one end (such as C2H5OH)
4) Molecules with an O at one end (such as H2O)
5) Molecules with an N at one end (such as NH3)

Nonpolar Molecules have:
6) All elements (such as O2)
7) Most carbon compounds (such as CO2)


H2S doesn't following any rules from 1 - 5 above so it's nonpolar.

HCL is polar (see rule #2)

CH4 is nonpolar (doesn't follow rules 1-5)

NH3 is polar (see rule #5)

Make sure you pick my answer as the best one. Thanks! ;)

Answer 3

ch4 İs nonpolar because the h pull the carbon directly at the opposite sides so c moves to nowhere

hcl is polar because cl is more electronegative

h2s is polar (it is special as h2o)not so sure

nh3 is polar

Answer 4

CH4 because it is bonded through dipersion and its lewis structure is symetrical.

Answer 5

CH4, methane, is non-polar.

Answer 6

yes its CH4
