Question
Consider the following three-dimensional ball and stick diagram: What is the electron-pair geometry around the central atom of the molecule represented by this diagram? a. linear b. tetrahedral c. trigonal planar d. trigonal pyramid Which of the following molecules is/are nonpolar? a. CH_4 b. CH_3 CI c. CH_2 CI_2 d. CHCI_3 What is a lone pair in a Lewis diagram? a. A bonding pair of electrons. b. A shared pair of electrons. c. A molecule with only two electrons. d. An unshared pair of electrons.Explanation / Answer
Q.5 trigonal planar
trigonal planar is a molecular geometry model with one atom at the center and three atoms at the corners of an equilateral triangle, called peripheral atoms, all in one plane.
Q .6 Methane (CH4) The charges all cancel out each other by equal distrubution in 4 H
Q.7 answer is d.
lone pair refers to a pair of valence electrons that are not shared with another atom and is sometimes called a non-bonding pair. Lone pairs are found in the outermostelectron shell of atoms. They can be identified by using aLewis structure.
