1organic reaction constitute of
substrate+attacking reagent which gives product +by product
2rate of organic reaction is proportional to what
stability of intermediate
3types of bond fission
homolytic , heterolytic
4in homolytic fission what about (bond fission, electronegativity,which intermediate is formed, and under what conditions it can take place(5)
symmetric bond fission, electronegativity should be comparable,free radicle,high temperature,electric current, presence of light, peroxide,non polar solvents
5heterolytic fission (bond fission which is the intermediate what are the conditions(2))
unsymmetric bond fission,intermediate cation/anion (ions) , conditions:large difference in electronegativity,polar solvent
6carbon free radical (how many pair of electron, hybridization, shape,octet or not, stability,charge,parallel or diamagnetic, electron deficiency or not
3pair of electron(3BP+0LP),sp2,Trigonal planar, incomplete octet, unstable, neutral, paramagnetic, electron deficient
7carbon cation (how many pair of electron, hybridization, shape,octet or not, stability,charge,parallel or diamagnetic, electron deficiency or not )
3 electron pair(3BP+0LP),sp2, Trigonal planar, incomplete octet, unstable,+ve charge, diamagnetic, electron deficient (here it is electrophile but carbon free radicle is not electrophile even though there is deficiency of electron)
8carbanion (how many pair of electron, hybridization, shape,octet or not, stability,charge,parallel or diamagnetic, electron deficiency or not ) also give an example for this
4 electron pair (3B+1LP),sp3,Trigonal Pyramidal,octet complete, unstable (cause of -ve change),-ve charge, diamagnetic, electron rich(nucleophile) example grignard reagent R-Mg-X
9what are carbenes(also example,how is it formed), in which reactions is formed(named),
Carbon with two unshared electron example:dichlorocarbene(:ccl2) CHcl3+KOH --->:ccl2 , Reimerteimann reaction and carbylamine reaction
10spin multiplicity equation and which are two carbenes based on it
2S+1(triplet carbene,singlet carbene)
11what are nitrenes
Nitrogen with two unshared electron
12benzyne (tell about resonance and stability)
no resonance and highly unstable
13which are electron displacement effects (4)
inductive, electrometric, resonance, hyperconjugate effect
14factors affecting the stability of reaction intermediates
inductive, resonance, hyperconjugative effect
15reaction mechanism:type of functional isomerism
tautomerism
16inductive effect (+I,-I)
+I electron releasing group, -I electron withdrawing group
17+I group decreasing order
CH2- >NH- > O- >COO- > 3°Butyl > Isopropyl>ethyl>methyl(CT3>CD3>CH3)
18-I effect group in decreasing order
NF3+ >NH3+ >NO2> CN > COOH > X(HALOGEN)> O-R >O-H>spcarbon(thripebond)>NH2>phenyl >sp2 carbon (double bond)
19electronegativity of (O, sp carbon,sp2 carbon, sp3 carbon ,and nitrogen) in decreasing order
O>sp carbon>N>sp2 carbon>sp3 carbon
20priority for looking stability
1.electronegativity to which charge is attached, 2.Degree of carbocation/carbanion 3.+I/-I effect 4. dnp rule(distance,number,power rule)
