Why is free radical sp2 hybridization?

Hint: The carbon atom has the molecular hybridization of SP2 and its free radical is formed by the homolytic bond cleavage, leading to the cleavage in such a way that electrons involved in bonding are split equally. Carbon atomic number is 6 and its hybridization is 1S2,2S2,2P2 .

Why is hybridization in CH3 and CF3 different?

CH3 has 3 sigma bonds and it’s hybridization is sp2 and it’s shape is planer while CF3 has hybridization sp3 and has pyramidal shape.

What is the hybridization of carbon atom in methyl free radical?

A methyl free radical consists of a carbon atom bonded to three hydrogen atoms and with one extra unpaired electron. This unpaired electron is highly reactive and thus is not included in the hybridization. So the hybridization of the carbon atom is sp2 in the methyl free radical.

What are free radicals explain the structure of alkyl free radicals giving hybridisation?

The unhybridised p orbital which lies in the plane at right angle to the plane of hybrid orbitals carries the odd electron. The bond angle around the carbon carrying the odd electron is nearly 120° each. Thus alkyl free radicals such as methyl radicals are planar.

Why is methyl radical sp2 hybridized?

In case of methyl radical the Carbon atom has 3 bond pairs and one odd electron which is present in one of the p orbital and this p orbital does not involve in hybridisation. Thus the carbon in methyl radical involves in sp2 hybridisation.

Do radicals have hybridization?

Radicals have the possibility of undergoing hybridisation and e.g. ending up in an spn orbital (examples: radicals on sp3 hybridised bridgehead atoms; phenyl radical). The radical is delocalised across two carbon atoms making the overall system more stable than if it weren’t.

Why CH3 radical is planar and CF3 radical is pyramidal?

Of the two free radicals, methyl (•CH3) and trifluoromethyl (•CF3), one is planar, the other pyramidal. In this extreme, the orbital is 25\% s in character; therefore, it is the CF3• which is pyramidal and the CH3• which is planar.

What is the hybridization of methyl anion?

The methyl anion has the molecular formula of $ C{{H}_{3}}^{-} $ . In this molecule we have one lone pair and three bond pairs with a negative charge on the carbon atom. This molecule is $ s{{p}^{3}} $ hybridised. It has a tetrahedral geometry.

Is a methyl group sp3?

all carbon atoms are sp’ hybridized. ring-carbon atoms are sphybridized and the methyl group is sp3 hybridized.

What are free radicals which is the most stable free radical and why?

Allyl radical is in turn less stable than benzyl free radical. Therefore, the most stable free radical is benzyl free radical. Hence the correct option is (B).

What are free radicals justify the stability of the aliphatic primary secondary and tertiary free radicals?

Stability increases in the order methyl < primary < secondary < tertiary. Free radicals are stabilized by resonance. Free radicals are stabilized by adjacent atoms with lone pairs. Free radicals increase in stability as the electronegativity of the atom decreases.

What is the hybridization of trifluro methyl radical in sp3?

In trifluro methyl radical hybridization is sp3 because F is present which is very electronegative element so it attracts an unpaired electron towards itself and add it in hybridization due to which hybridization get shift from sp2 to sp3. How does mental health impact lung cancer symptoms?

What is the hybridization of ins in methyl free radical?

in methyl free radical the hybridization is sp2 because it has 3 bond pairs and one unpaired electron which is very reactive so in hybridization it is not included and 3 bond pairs are present so one goes with s and other 2 with p.

What is the hybridisation of CH3 and CF3 radicals?

But in case of substituted radicals like trifluoro methyl free radical increasing fluorine substitution causes the radical to go from planar sp2 hybridisation ( as in .CH3) to tetrahedral, sp 3 hybridisation in (.CF3 )radical.

How many electron groups are involved in sp3d2 hybridization?

Octahedral: Six electron groups involved resulting in sp3d2 hybridization, the angle between the orbitals is 90°. Explain sp3 Hybridization in Methane? The 2s and all the three (3p) orbitals of carbon hybridize to form four sp3 orbitals.
