Protein are nitrogeneous organic compoun...

Protein are nitrogeneous organic compound having very high molecular mass. They are polyamides formed from `alpha`-amino acid. The bond formed between two amino acid is called peptide bond `-underset(O) underset(||)C-NH-`. The product obtainded by this peptide bond formation are called peptide and they may be divided as di, tri ,tetra, penta peptide.
Which statement are correct about peptide bond?
1. `-overset(O)overset(||)C-NH-` group is planar.
2. `C-N` bond length in protein is longer than usual bond length of `C-N` bond.
3. `C-N` bond length in protein is samller than usual bond length of `C-N` bond
