In which compound is hydrogen bonding found?
Hydrogen bonding occurs only in molecules where hydrogen is covalently bonded to one of three elements: fluorine, oxygen, or nitrogen. These three elements are so electronegative that they withdraw the majority of the electron density in the covalent bond with hydrogen, leaving the H atom very electron-deficient.
What types of atoms make a ionic bond?
An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal. A covalent bond involves a pair of electrons being shared between atoms.
What bond is the shortest?
triple bonds
Are single bonds the strongest?
1 Answer. No, but the type of bond that forms a single bond is the strongest.
Are double or single bonds more acidic?
I know that triple bonds are more acidic than double bonds, and double bonds are more acidic than single..but why?? OP beware the other answers. The correct answer is that the triple bond carbon is sp hybridized, meaning that it has much more s character than an sp3 orbital.
Does a double bond increase acidity?
If the conjugate base has a charge which can interact with adjacent double bonds or p orbitals, its stability will increase. This leads to increased acidity of the conjugate acid.
Do double bonds make it more basic?
when you add in the double bond, you get the resonance I pictured above. Now, that proton (hydrogen) is held tighter to the molecule because of the partial negative nearby it. Hence, it won’t be able to donate the proton as easily = less acidic = more basic.
How do you know which molecule is more basic?
First, scan the molecule for all non-halogen atoms with lone pairs (usually N and O). Second, imagine protonating each candidate atom and draw its conjugate acid. Third, identify the weakest conjugate acid. The protonated atom in the weakest conjugate acid is the most basic atom in the original molecule.
Is S or O more basic?
Oxygen is more electronegative than sulfur, so it is more likely to accept a proton. Therefore, the OH anion is more basic than the SH anion. Also, the conjugate acid of the SH anion, H2S, is more acidic than the conjugate acid of OH, H2O. In short, H2S is more acidic than H20, so OH must be more basic than SH.
Is CH3 acidic or basic?
CH2=CH2 HCI CH3COOH Solution CH3- is the base because it accepts a proton, forming its conjugate acid, CH4. H2O is the acid because it donates a proton, forming its conjugate base, OH.
Which is most basic compound?
It is very much like a primary amine and lone pair of electrons on N are easily available. Hence, the most basic compound is Benzylamine and the correct option is D.
Which compound is the least basic?
NI3 is least basic because Iodine has vacant d orbital hence it can accept lone pair of electrons from Nitrogen and help in back bonding. Also, basicity decreases down the group and in this manner as well NI3 is less basic than any other given compounds.
