This material does not contain any Class 1 Ozone depletors. It is an intensive property, which means the amount of material tested is irrelevant. The Testing of the Melting Points of p-dichlorobenzene and naphthalene Introduction: Melting point temperature is a physical property of pure substances. Also available in Class 12 Medical - Physical Properties of Haloalkanes and HaloarenesClass 12 Engineering - Physical Properties of Haloalkanes and Haloarenes. It liquefies when mixed with camphor, phenol and salol. It is known that dipole-dipole interactions are stronger than the London dispersion forces thereby making the boiling point of m- dichlorobenzene greater than that of p- dichlorobenzene. 1,2-Dichlorobenzene is well absorbed via the oral route. blue (2) purple (1) ... EPA TCLP Base Neutral Dichlorobenzene. Melting Point (°C) less than 0 (4) 0 - 100 (27) 101 - 200 (3) 201 - 300 (5) 301 - 400 (1) Color. It requires high energy for p-dichloro benzene than o- & m- dichloro benzene to break these bonds during dissolution and boiling. In rats, absorption of 1,2-dichlorobenzene from the gastrointestinal tract was considered complete at doses of 5 and 50 mg/kg bw but incomplete (83% absorption) at 250 mg/kg bw. 1,3- Dichlorobenzene is a colorless liquid used to make herbicides, insecticides, medicine, and dyes. 1 Product Result ... Nitro-p-dichlorobenzene Linear Formula: Cl 2 C 6 H 3 NO 2. It will attack some forms of plastics, rubber and coatings. This is because, p-isomer has symmetrical structure therefore, its molecules can easily be packed closely in crystal lattice.. p-Dichlorobenzene is more symmetrical than o-and m-isomers. 1,4-Dichlorobenzene ≥99% CAS Number 106-46-7. (NTP, 1992). Empirical Formula (Hill Notation) C 6 H 4 Cl 2. Therefore, more energy is required to break the crystal lattice of p-dichlorobenzene. NACRES NA.22 MDL number MFCD00000604. EC Number 203-400-5.

Hence certain dipole-dipole interactions are generated in m-dichlorobenzene compared to the London dispersion forces generated in its p- counterpart. Therefore, more energy is required to break the crystal lattice of p-dichlorobenzene. For this reason, it fits more closely than o-and m-isomers in the crystal lattice. Hence, it has stronger intermolecular forces of attraction than o-and m-isomer. Hence, p-Dichlorobenzene has higher melting point than those of o- and m-isomers. Therefore, more energy is required to break the crystal lattice of p-dichlorobenzene.As a result, p-dichlorobenzene has a higher melting point and … There are three dichlorobenzene isomers- 1,2-dichlorobenzene, 1,3-dichlorobenzene, and 1,4-dichlorobenzene.Dichlorobenzenes do not occur naturally. PubChem Substance ID 24893960. EC Number 203-400-5.
