We should know that S orbitals hold electrons more tightly to nucleus than P orbitals . This implies that S orbitals are effectively more electronegative . Now, in sp2 carbon the character of each orbital has 1/3 or 33% of s orbital characteristics whereas in each sp3 orbital s character is 1/4 or 25% . So sp2 has more s character and therfore more electronegativity.

What is the hybridization at each carbon atom in the molecule H8C6?
You will need to supply a structural formula for this question to be answered. Or you could simply count the number of other atoms bonded to each carbon: 4 means it's sp3, 3 is sp2, and 2 is sp.
Ethane a Alkene?
The carbon of the carbon-carbon double bond is sp2hybridized. Take CH3CH=CHCH3 as an example: the C of the double bond is sp2 hybridized, cause the C has 3 bond pairs (2 single bonds+1 double bond).The hybridization state of a carbon can be calculated by spn-1 ,where n is the no. of bond pair , and n is stand for a single bond or a double bond or a lone pair electrons.Take CH2=NH as an example: both the N and the C is sp2 hybridized cause for the N, it has one single bond, one double bond and a pair of lone pair electrons.
What is the bond angle between the oxygen atoms in the carbon dioxide molecule?
The bond angle between the oxygen atoms in a carbon dioxide molecule is 180 degrees. This is because the molecule has a linear geometry, with the carbon atom in the center bonded to each oxygen atom on opposite sides, creating a straight line.
Can an ether contain a carbonyl group?
The carbons adjacent to the oxygen and the oxygen itself are less charged than the oxygen ad its attached carbon in a carbonyl group. The oxygen always carries a delta negative charge and the carbons a delta positive charge, but it is considerably lower in an ester than in a carbonyl. This is partly due to the double bond in the carbonyl making the bond electron dense and more polarisable.
What is molecular shape of C2H5Cl?
The molecular shape of C2H5Cl (chloroethane) is tetrahedral. The central carbon atom has four electron domains - three bonding pairs with hydrogen atoms and one bonding pair with chlorine. This results in a tetrahedral geometry with a bond angle of approximately 109.5 degrees.
Which carbon is more electronegative sp3 sp2 sp?
sp carbons are more electronegative. The larger the 's' character of the atom, the closer the electrons are held to the nucleus. sp3 carbons are the least electronegative as the 'p' character forces the electrons to exist further from the nucleus, decreasing electronegativity.
Is propanol more polar than acetone?
Ethanol is more polar than acetone because in acetone the carbon that the O is bonded to is sp2 hybridized where as the carbon that the O is bonded to in ethanol is sp3 hybridized. Since the sp2 carbon is more polar than the sp3 carbon, acetone has a lower dielectric constant. Hope this helps.
What is the hybridization of a carbon that is in the alkene and aromatic functional groups?
In an alkene, the carbon is sp2 hybridized (trigonal planar with 120° bond angles), while in an aromatic ring, the carbon is sp2 hybridized due to resonance. Therefore, a carbon in a molecule with both alkene and aromatic functional groups would also be sp2 hybridized.
Which substance show maximum sp2 carbon atoms?
Aromatic compounds, such as benzene, typically have the maximum number of sp2 hybridized carbon atoms. In benzene, all six carbon atoms are sp2 hybridized, with each carbon forming a sigma bond with two neighboring carbons and one pi bond above and below the ring.
What is the hybridization of c2h4?
The carbon atoms are sp2 hybridised.
What are the hybridization of the carbon atoms in CH3 CH2 COH?
The C in h3c is sp3 hybridized The c in ch is sp2 hybridized the c in ch2 is sp2 hybridized
What is the hybridization of the carbon atom as it is contained in carbon dioxide?
The carbon atom in carbon dioxide is sp2 hybridized. This means that there are three electron pairs around the carbon atom, resulting in trigonal planar geometry.
What is the hybridization of the central atom of COCl2?
The central atom in COCl2 is carbon. The carbon atom is sp2 hybridized in COCl2, meaning it has three electron pairs in sp2 hybrid orbitals and forms sigma bonds with three surrounding atoms in a trigonal planar geometry.
Which is more reactive sp2 or sp3 carbon?
Sp2 carbon is more reactive than sp3 carbon. This is because sp2 hybridized carbon has a higher degree of s-character (33.3%) compared to sp3 hybridized carbon (25%). The higher s-character in sp2 carbon results in stronger bonds and increased reactivity towards nucleophiles and electrophiles.
What is state of hybridisation of c in carbon free radical?
In a carbon free radical, the carbon atom has three unpaired electrons in its outer shell, indicating sp2 hybridization. This allows the carbon atom to form three covalent bonds with other atoms.
Why would you expect a C-C sigma bond formed by sp2-sp2 overlap to be stronger than a sigma bond formed by sp3-sp3 overlap?
A C-C sigma bond formed by sp2-sp2 overlap is stronger than one formed by sp3-sp3 overlap because the sp2 hybrid orbitals have a greater s-character (33%) compared to sp3 orbitals (25%), leading to more effective overlap and stronger bonding. This higher s-character causes the sp2-sp2 bond to be shorter and stronger than the sp3-sp3 bond.
What is the hybridization of each atom in propenoic acid?
In propenoic acid (also known as acrylic acid), the carbon-carbon double bond and the carbonyl group result in sp2 hybridization for both carbon atoms in the double bond and the carbonyl carbon. The oxygen atom in the carbonyl group has sp2 hybridization, while the remaining carbon atoms have sp3 hybridization.
