Explain heat of formation
Although both molecules have bridgehead double bonds, the double bond in compound B is more twisted, and a model of this molecule is more complex to build. Consequently, compound B is less stable and thus would have the greater (more positive or less negative) heat of formation.
Delocalisation of electrons in conjugated system is called resonance. For example there is delocalisation of electrons in benzene ,hence we write kekule structure for benzen.
The number of unpaired electrons in nitrogen is: (1) 1 (2) 3 (3) 2 (4) None of these Ans: 3
What is the difference between reaction stoichiometry and composition stoiciometry?
Physical properties of Succinic Acid (a) Succinic Acid is a white crystalline solid. It melts at 188° C (b) Succinic Acid is less soluble in water. It is comparatively more
Symmetry is a property of molecules having more than one atom of the same kind, with equal bond lengths and/or bond angles. As like the high symmetry of the SF6 molecule (Fig. 1. a
Explain the Sensory Evaluation We begin our discussion on sensory evaluation by first understanding what we mean by sensory evaluation. Sensory evaluation is a scientific disc
Structure of benzene - Kekule structure It has a special structure, which is even though unsaturated even then it usually behave as a saturated compound. (i) Kekule's struct
Q. What is basic diffrence between heat and temperature? Ans. Heat is energy which flows from hot objects to cooler ones. It flows because of the temperature difference betw
