Double and triple bonds each have another type of bond different from the initial single bond present between the two bonded atoms. The sigma bond, the initial single bond, is formed through a head-on overlap of two atomic orbitals. Rotation about this bond does not change the overlap, and so rotation is allowed.
But double and triple bonds have pi bonds, formed by side-on overlap between the atomic orbitals (typically either p or d orbitals). These bonds surround the sigma bond and were rotation to occur, the orbitals involved with the pi bonds would cease to overlap and these bonds would be broken.
Therefore, the specific bond that restricts rotation about the axis of a double or triple bond would be the pi bond(s) involved.
What else can I help you with?
Are carbon bonds freely rotational?
Single bonds to carbon are usually freely rotational, but double and triple bonds usually are not. Rotation can also be hindered by steric factors; the carbon-carbon single bonds in cyclopropane, for example, are not freely rotational because of the constraint of the cyclic structure.
How do double bonds affect bond angles in molecules?
Double bonds in molecules typically result in a rigid planar structure, which can affect bond angles. The presence of a double bond restricts the rotation around the bond, leading to a fixed bond angle of approximately 120 degrees. This can influence the overall shape and geometry of the molecule.
Which one of the following statements concerning single double and triple bonds is correct?
Double bonds consist of one sigma bond and one pi bond, while triple bonds consist of one sigma bond and two pi bonds. Double bonds are shorter and stronger than single bonds, while triple bonds are shorter and stronger than double bonds.
What bond is strongest single double or triple?
The triple bond is the strongest among single, double, and triple bonds. It consists of one sigma bond and two pi bonds, making it more difficult to break compared to single or double bonds. Triple bonds also exhibit the shortest bond length and highest bond energy.
Is the single double or triple bond the strongest?
Bond strength follows this trend triple>double>single....Triple bonds have 2 pie bonds and 1 sigma bond, Double bonds have 1 pie bond and 1 sigma bond and single bonds have 1 sigma bond.
What bonds restrict rotation about the axis of double or triple bonds?
Double and triple bonds restrict the rotation around the axis of the bond, resulting in more rigid molecules. These are typically known as Pi bonds.
Does aluminium sulfide have double or triple bonds?
Aluminium sulfide has two double bonds.

Are the bonds between carbon and chlroine single double or triple bonds?
single
Can carbon only form single bonds?
No. Benzene (C6H6) is a base for very many carbocyclic compounds. It contains six carbon atoms in a hexagon. The bonds between the carbon atoms are alternately single and double. The fourth is with the hydrogen. Acetylen (C2H2) jas a triple carbon-to-carbon bond.
Is a conjugated double bond and triple bond a diene?
No, a conjugated double bond and a triple bond do not constitute a diene. A diene specifically refers to a molecule containing two double bonds. While conjugated systems can involve double and triple bonds, a diene must have two adjacent double bonds, whereas a triple bond alters the bonding structure and does not fit the definition of a diene.
What is the chemical difference between a saturated and an unsaturated fats?
Unsaturated fats have double or triple carbon bonds.
What type of bond is the longest triple double or single?
Triple bonds are the longest among single, double, and triple bonds. Triple bonds have the shortest bond length due to the increased number of shared electron pairs between the atoms, making the bond stronger and shorter in length.
