Iso-butene (iso-C4H8) is an important raw material in chemical industry, whereas its efficient separation remains challenging due to similar molecular properties of C4olefins. The ideal adsorbent should possess simultaneous high uptakes for 1,3-butadiene (C4H6) and n-butene (n-C4H8) counterparts,...
The empirical formula is the simplest formula for a compound, defined as the ratio of subscripts of the smallest whole number of elements in the formula. It's also referred to as the most basic formula. The formula of a substance expressed with the smallest integer subscript is called an emp...
Process for rendering organic high molecular weight polymers resistant to electrostatic chargeOrganic polymers are rendered resistant to electrostatic charge by incorporation of one or more substituted oxalic acid amides of formula where X is or-OR4, R is a C12- 24 alkyl, R1, R2 and R3 are ...
For the alkyne, C_{10}H_x, what is the correct number of hydrogens (x) in the chemical formula? Write the molecular formula for a straight-chain alkene with one double bond and seven carbon atoms. Write the molecular formula for a straight-chain alkene with on...
In formula 1 above, R preferably represents a C1 to C10 aliphatic, alicyclic or aromatic hydrocarbon radical such as ethyl (Et), phenyl, isopropyl, butyl, propyl, n-butyl, i-butyl, t-butyl, hexyl, cyclohexyl, octyl, napthyl, etc. Non-limiting, illustrative examples of formula (1) and ...
Differentiate between the molecular formula and Lewis formula of water. Lewis Structure: Lewis dot structures sometimes called electron dot structures are diagrammatic views of how atoms in a molecule are chemically bonded together. There is also a display of how many lone pairs are present ...
(A-2) represented by the below-shown general formula III on a support (A-1) prepared by a reaction of an organomagnesium compound represented by the below-shown general formula I soluble in an inert hydrocarbon solvent with a chlorinating agent represented by the below-shown general formula ...
Molecular geometry is based on the valence shell electron pair repulsion, which predicts the three-dimensional structure of compounds. Valence shell electron pair repulsion (VSEPR) theory involves the number of electron pairs surrounding the central atom to determine the molecular geometry. The different...
