Why CICH2COO is more stable than CH3COO? |
| Answer» I guess you have forgotten to show the charges . If you meant CH3COO- AND ClCH2COO-I have a answer.It\'s due to -I effect . The Cl atom shows -I effect and hence withdraws electrons from the conjugated system , reducing the - ve charge and hence increasing stability . ? | |

Difference between resonance and hyper conjugate? |
| Answer» The main difference between hyperconjugation and resonance is that hyperconjugation involves the interaction between a sigma bond and a p orbital or a pi bond whereas resonance involves the interaction between pi bonds. In a covalent compound, two major types of chemical bonds can be observed between atoms.Hyperconjugation can be used to rationalize a variety of chemical phenomena, including the anomeric effect, the gauche effect, the rotational barrier of ethane, the beta-silicon effect, the vibrational frequency of exocyclic carbonyl groups, and the relative stability of substituted carbocations. | |

The two condition for the linear combination of atomic orbital? |
| Answer» The overlap of atomic orbitals means their partial merger,because of which their certain portion becomes common to both of them.The important conditions required for the linear combination of atomic orbitals to form molecular orbital are as follows:a) The atomic orbital with one electron (compeletely half filled) can take part in combination or overlapping.b) During the time of overlap,the combining orbitals must have opposite spins of electrons.c) The combining atomic orbitals must have the same or nearly the same energy. This means that in a homonuclear molecule, the 1s-atomic orbital of an atom can combine with the 1s-atomic orbital of another atom, and not with the 2s-orbital.d) The overlapping must be maximum as far as possible. | |
