No tertiary alcohols can contain this group because no tertiary alcohols can have a hydrogen atom attached to the carbon with the -OH group. No tertiary alcohols give the triiodomethane (iodoform) reaction. Which compounds can give iodoform test? Compounds That Give Positive Iodoform Test Acetaldehyde. Methyl Ketones. Ethanol. Secondary AlcoholsRead More →
ϕ denotes the image of H under ϕ ≤ denotes subgroup. That is, group homomorphism preserves subgroups. Is the image of a homomorphism a subgroup? Let and be groups and let φ : G → H be a group homomorphism. Are Homomorphisms bijective? An isomorphism of topological spaces, called homeomorphismRead More →
The reason why the hydrogen can be placed in both group 1 and group 17 is that it resembles Alkali metals in some of its properties like it can easily form cations so, it can be placed in Group 1 of periodic table but it also resembles Halogens in itsRead More →

In mathematics, especially group theory, the centralizer (also called commutant) of a subset S in a group G is the set of elements of G such that each member commutes with each element of S, or equivalently, such that conjugation by leaves each element of S fixed. What is aRead More →
Exopeptidase: An enzyme that catalyzes the cleavage of the terminal (last) or next-to-last peptide bond from a polypeptide or protein, releasing a single amino acid or dipeptide. What is the difference between endopeptidase and Exopeptidase? Endopeptidase or endoproteinase are proteolytic peptidases that break peptide bonds of nonterminal amino acids (i.e.Read More →
Alkynes are organic molecules made of the functional group carbon-carbon triple bonds and are written in the empirical formula of CnH2n−2. They are unsaturated hydrocarbons. Is a hydrocarbon a functional group? Hydrocarbons. Hydrocarbons are a class of molecule that is defined by functional groups called hydrocarbyls that contain only carbonRead More →
thallium (Tl), chemical element, metal of main Group 13 (IIIa, or boron group) of the periodic table, poisonous and of limited commercial value. Like lead, thallium is a soft, low-melting element of low tensile strength. Freshly cut thallium has a metallic lustre that dulls to bluish gray upon exposure toRead More →
