B) Clasifica las siguientes reacciones químicas apareando con el número que le corresponda. 1- Síntesis NaOH + HCL → NaCL + H2O
2-Descomposición AgNO3 + KCL → KNO3 +AgCL 3- Doble descomposición 2Na +CL → 2NaCL
4- Desplazamiento FEO2 → FE + O2
5- Doble desplazamiento AgNO3 + HCL → AgCL + HNO3
6-Neutralizacion Mg + CuSo4 → MgSo4

Explanation:

(a) melting point of S,S-hydrobenzoin should be 140°C. Since S,S-hydrobezoin and R,R-hydrobenzoin are enantiomeric pair so that their melting point and boilong point should be same.

(b) different melting point,

Racemic mixture must have different melting point in comparison to the pure enantiomers.

considering a racemic mixture, individual enantiometer possesses a greater affinity for its kind of molecules than for those of the other enantiometer
