4.It has one lone pair of electrons on A.correct5.It has two single bonds and two doublebonds.6.It is an anion.7.It is a non-polar molecule.
Explanation:The Lewis structure isAY01810.0 pointsWhich of the following compounds contains aσbond formed from the overlap of 1sandsp3atomic orbits?LiCl>LiBrcorrect
5.C2H4Explanation:01910.0 pointsPredict the bond angle in the nitrite ion,NO2.10.0 pointsA molecule has one lone pair of electrons onthe central atom and three atoms bonded tothe central atom.The central atom followsthe octet rule. What is its electronic arrange-ment and its hybridization?4.slightly less than 109.5 degrees5.180 degrees6.slightly less than 120 degreescorrectExplanation:N is the central atom. One O atom makesa single bond to N and the other makes adouble bond to N. This means there are TWOdifferent resonance structures.Additionallythere is a lone pair on the N atom.There are 3 RHED around N so the elec-tronic geometry is trigonal planar.As oneRHED is a lone pair, the molecular geometryis bent and the O-N-O bond angle is a littleless than 120 degrees.

Version 038 – Exam 2 – McCord – (53130)7
02210.0 pointsThe compound ClF5(where Cl is the centralatom) has an electronic geometry of octahe-dral.What would be the quantities for theLewis dot formula?
The number of electrons needed in this casemust be adjusted for an expanded octet forthe central atom, chlorine, which will have6 pairs of electrons (12 total) for its valenceshell.Each of the fluorines will have a trueoctet. Thus
