एक्सप्लेन द कंडीशन फॉर द फॉर्मेशन ऑफ सिगमा एंड पी बॉन्ड ?
Answers
Explanation:
The hybridization model helps explain molecules with double or triple bonds (see figure below). Ethene (C2H4) contains a double covalent bond between the two carbon atoms, and single bonds between the carbon atoms and the hydrogen atoms. The entire molecule is planar.
The electron domain geometry around each carbon independently is trigonal planar. This corresponds to sp2 hybridization. Previously, we saw carbon undergo sp3 hybridization in a CH4 molecule, so the electron promotion is the same for ethene, but the hybridization occurs only between the single s orbital and two of the three p orbitals. This generates a set of three sp2 hybrids, along with an unhybridized 2pz orbital. Each contains one electron and so is capable of forming a covalent bond.
Answer:
sigma bonds are a result of the head to head overlapping of atomic orbitals whereas p bonds are formed by the lateral overlap of 2atomic orbitals
