Four molecules have carbon as the central atom and hydrogen atoms around it. which shape would give rise to a polar molecule?

a) linear

b) trigonal planar

c) bent

d) tetrahedral

D) Tetrahedral

Explanation:

Hello,

Tetrahedral is a molecular shape that turns out when four bonds and no lone pairs around the central atom in the molecule. The bonded atoms to the central atom lie at the corners of a tetrahedron with 109.5° angles between them. The molecules with an tetrahedral electron pair geometries have hybridization at the central atom. For instance, both ammonium ion () and methane () have a tetrahedral molecular geometry.

Best regards.

that tool would be a compass

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
