Carbon, C, is a nonmetallic element, grey solid. It is found in nature as graphite (specific gravity2.25), diamond(specific gravity 3.51), and coal (specific gravity 1.88). Carbon is found in all living things, is insoluble in common solvents,and forms an almost infinite numberof organic compounds. Anaturally occurring radioactive isotope,14C, has a half-life of 5780 years and is used in archaeo logical investigations to date artifacts and ancient documents. Other uses of carbon depend on its f
Diffusion of carbon from ferrite to cementite in the eutectoid transformation Why does the carbon of an alloy diffuse from ferrite (0.022% C) to cementite (6.70% C) during eutectoid transformations? I know that the diffusion of a generic species (e.g. of atom A) carries A from regions where the amount of A is higher to regions where the amount of A is lower. I found this sen...more+Aug 15 2021
How can nucleophilic substitution happen at the sp2-hybridised carbon of 4-chloropyridine? Why can substitution of the C–Cl bond occur at the sp 2 -hybridized carbon in the following reaction (taken from Clayden et al. , Organic Chemistry (2nd ed.), p 700)? Ordinarily, S N 1- and S N 2-type reactions should not occur at sp 2 centres, as described here: Why do SN1 and SN2 reaction not oc...more+Aug 09 2021
Why and how does carbon hybridize itself according to its need? [duplicate] Hybridization is part of the language chemists use to speak to one another. When someone says that a carbon atom is s p X 2 " style="position: relative;" tabindex="0" id="MathJax-Element-16-Frame" class="MathJax" s p X 2 s p X 2 hybridized, it's a shorthand way of telling others that there is a p-o...more+Jul 03 2021
What is the carbon content, by weight, of vegetable oil? I have only a high school understanding of chemistry, so please bear with me and my ham-fisted question. I’m trying to understand the carbon content in vegetable oil. I get that various oils have differing densities, so the measure needs to be “by weight”. Molecular weight doesn’t help, I need ...more+May 30 2021
