2. Which one of each of the following pairs can form intermolecular hydrogen bonds? Explain your choice, and then draw the H-bonded structures for your choice. Hint: Draw the "expanded" chemical structure of each of the molecules to make your drawing, and the H-bond locations, clearer. (CH3)2NHjor (CH₂)2N.. Because it has nihoyen atom with pair of electu can act like a election accept. in hydrogen! Because it has (-OH) BHOCH₂CH₂CH2OH or FCH₂CH₂F
Formal Charges
Formal charges have an important role in organic chemistry since this concept helps us to know whether an atom in a molecule is neutral/bears a positive or negative charge. Even if some molecules are neutral, the atoms within that molecule need not be neutral atoms.
Polarity Of Water
In simple chemical terms, polarity refers to the separation of charges in a chemical species leading into formation of two polar ends which are positively charged end and negatively charged end. Polarity in any molecule occurs due to the differences in the electronegativities of the bonded atoms. Water, as we all know has two hydrogen atoms bonded to an oxygen atom. As oxygen is more electronegative than hydrogen thus, there exists polarity in the bonds which is why water is known as a polar solvent.
Valence Bond Theory Vbt
Valence bond theory (VBT) in simple terms explains how individual atomic orbitals with an unpaired electron each, come close to each other and overlap to form a molecular orbital giving a covalent bond. It gives a quantum mechanical approach to the formation of covalent bonds with the help of wavefunctions using attractive and repulsive energies when two atoms are brought from infinity to their internuclear distance.
Can you help me correcting question 2?I have the answers right, I just need to do what these notes say.
Notes 1:(you have the right choices, but note that in your drawings you should have two molecules of each, since the H bond forms between molecules.)
Notes 2:(I meant two of the same molecule - the circled one in each pair. Then draw the hydrogen bond as a dotted line between appropriate atoms between them.)
