How many single bonds are in the Lewis structure for CH4? Given the following Lewis structure: 1. How many unshared pairs of electrons are present in this molecule? A) 0 B) 1 C) 2 D) 3 E) 4 2. How many electrons are shared between carbons 1 and 2?
The angles with which different bonds of a molecule lie in space is called the bond angle and it is influenced by many other factors like geometry, lone pairs and so on.Answer and Explanation: Based on the VSEPR theory, SF4 molecule is said to have a See-saw geometry in space. The v...

How do polar molecules form hydrogen bonds? Which bond is the most polar: C-H, O-H, N-H, F-H? Is carbon disulfide polar? What does electronegativity have to do with polarity? a) Are there polar bonds in water? (Show EN for each of the bonds in the molecule) b) What is the ...
Methane (CH4) covalent bonding (Photo Credit : petrroudny43/Shutterstock) Ionic Compounds Ionic compounds are similar to covalent bonds, but differ in terms of how the electrons of the two atoms interact. Ionic compounds a formally defined as a grouping of atoms of more than one element connect...
The acidity of zeolite surface, according to balancing charge of cations, is strong sufficiently for assisting the cleavage of chemical bonds to a chemical reaction at molecular level, so as to, zeolites were employed as catalysts in many reactions such as NOx removal of exhaust gases from ...
A comparative study between the C−Au(111) and the S−Au(111) bonds allows us to establish a thermodynamic, structural, and electronic description of the aromatic and aliphatic chemisorption. Enlightening insight emerges from the projected density of states, which delivers a natural interpretation...

但是他学习上不投入,上课开小差,东张西望,搞小动作,惹周围同学,有时下座位去惹人家。下课更是忙得不得了,爬高上梯,胆子太大_『。上课不遵守纪律,老师批评其行为,他就要打老师。情绪极不稳定,动不动就发脾气,经常与同学发生冲突争执,更严重的是经常逃学、说谎、偷同学邻居物品、威胁欺负弱...
as some functional groups are more soluble in water than others. As the carbon chains within the homologous series become longer, the boiling point of the compound changes. While it increases in many cases, if the carbon chain begins the form branches, the boiling point will begin to decrease...
