What is a single bond made of?
Sigma
What is a double bond made?
Sigma and Pi
What type of bond is made of a sigma bond?
Single bond
What type of bond is made of a sigma and pi?
Double bond
Which hybridisation leads to single bonds?
SP3
Which hybridisation leads to double bonds?
SP2
Which hybridisation leads to triple bonds?
SP
SP2 hybridisation leads to which type of bond?
Double
SP3 hybridisation leads to which type of bond?
Single
SP hybridisation leads to which type of bond?
Triple
Which bond has the shortest length, double or a single?
Double
Why is a double bond shorter than a single bond?
It contains sigma and pi. More electrons are shared between the atoms. Stronger attraction between the nucleus and the shared pair of electrons.
Why is double bond stronger than a single bond?
It contains sigma and pi. More electrons are shared between the atoms. Stronger attraction between the nucleus and the shared pair of electrons.
How is a pi bond made in a double bond?
Overlap of the spare P orbitals between two atoms
Overlap of the p orbitals leads to what type of bond?
Pi in double bond
