(c) Which molecule has the stronger N-N bond? An N atom has one lone pair i.e. From drawing the Lewis structure of N 2 H 4, we could identify that each nitrogen atom is s p 3 hybridized and uses two s p 3 orbitals to form N-H bonds and hydrogen has only one electron in its 1s orbital. To be the best lewis structure, charges of atoms should be minimized. If there are only four bonds and one lone pair of electrons holding the place where a bond would be then the shape becomes see-saw, 3 bonds and 2 lone pairs the shape is T-shaped, any fewer bonds the shape is then linear. Step 2 - Next thing is determining the central atom. Aniline is less basic than amines. The hybridization of the atoms in this idealized Lewis structure is given in the table below.

They have trigonal bipyramidal geometry. We will discuss why this happens below. In this case, the carbon atoms have three sigma bonds, and one bond making up the double bond. So, the two N atoms to complete their octet do the sharing of three electrons of each and make a triple covalent bond. Hybridization number is the addition of a total number of bonded atoms around a central atom and the lone pair present on it. b.) tetrahedral sp. NA. A '+' sign implies losing electrons and '-' means gaining. sp hybridization : This type of hybridization involves the mixing of one s and one p orbital resulting in the formation of two equivalent sp hybrid orbitals. help!!! If all the bonds are in place the shape is also trigonal bipyramidal. Remember that bonds, unlike sigma bonds, are made from p-orbitals.. One p-orbital is needed to make the double-bond to the other carbon. Chemists use hybridization to explain molecular geometry. (a) Draw Lewis structures for both molecules.
