reference to the following figure, which of the following statements is not true? a. The bond in the hydrogen molecule is formed by the overlap of 1s atomic orbitals. b. The overlap of electron waves represented by the atomic orbitals may result in constructive (in-phase) or destructive (out-of-phase) interference. c. In-phase overlap between two 1s orbitals results in a new orbital having higher energy than either of the s orbitals. This new orbital concentrates the electron probability between the two nuclei. d. Out-of-phase overlap between two 1s orbitals results in a new orbital having higher energy than either of the s orbitals. This new orbital places most of the electron probability to the left and right of the two nuclei. e. All of the above statements are true.
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.
In reference to the following figure, which of the following statements is not true?
a. The bond in the hydrogen molecule is formed by the overlap of 1s atomic orbitals.
b. The overlap of electron waves represented by the atomic orbitals may result in constructive (in-phase) or destructive (out-of-phase) interference.
c. In-phase overlap between two 1s orbitals results in a new orbital having higher energy than either of the s orbitals. This new orbital concentrates the electron probability between the two nuclei.
d. Out-of-phase overlap between two 1s orbitals results in a new orbital having higher energy than either of the s orbitals. This new orbital places most of the electron probability to the left and right of the two nuclei.
e. All of the above statements are true.
Bonds is formed by the overlapping of atomic orbitals.
The overlapping can be done in two ways : constructive(in phase) and destructive(out of phase)
In phase overlapping result in lower energy molecular orbitals than the two atomic orbital and electron density is concentrated between the two atomic nuclei
Out of phase overlapping result in genration of higher energy molecular orbitals than the two or orbitals and there is no electron density between the orbitals, electron density lies at both the ends of the atom nuclei.
