Give only typing answer with explanation and conclusion Consider the compounds below. First, identify if the compound is covalent or ionic. If covalent, identify the intermolecular forces that compound will have. Then, rank them based on their melting point – with 1 being highest, 5 being lowest. NaBr LiF H2S C2H6 H2O

Draw the condensed structure of an isomer of this molecule: CH3-CH2 -CH2 CH3 Click anywhere to draw the first atom of your structure.

In one of the two boxes below, draw a wedge and dashed wedge structure (picture) of CH3Cl that best illustrates the geometry about the central atom. In the other box, draw another picture of the model from a different angle (viewpoint).

Answer the following question.

For each of the following molecules in the list: 1) List the total number of valence electrons and then draw the Lewis dot structure. 2) Use the kits to make a model of each molecule or ion. (A specific ball may not exist for the type of atom that you are looking for. If this happens, use a ball for which the number of holes matches the number of electron areas needed.) 3) Name the electron pair geometry. 4) Name the molecular shape. 5) Draw a 3-D sketch of the molecular shape and list the bond angles. 6) If the molecule contains covalent bonds, indicate if it is polar or nonpolar. 7) When necessary, draw a polar arrow for each bond. 8) If the molecule is polar, draw an arrow next to the 3-D sketch indicating the direction of the dipole moment.

What does "penta-" mean? What does "di-" mean? The only exception for prefixes is when there is only one atom of the element. Example: CO is called Carbon Monoxide NOT MonoCarbon Monoxide Choose: first, second
