The definition of disubstituted is having two substituent atoms or groups in a molecule
Delicious77 [7]3 years ago
6 0

These definitions are the preferred ones to be used in Organic Chemistry. Note that some terms (such as configuration) have more than one interpretation.

<span>acid:</span> an agent able to produce positively charged hydrogen ions (H+). [Since the hydrogen ion is a bare proton, it usually exists in a solvated form (such as H3O+).]

<span>achiral: </span>not chiral. A compound (or object) that is superimposible on its mirror image. For example CH4.

<span>activation energy:</span> the miminmum energy which reacting species must possess in order to be able to form an 'activated complex', or 'transition state', before proceeding to the products. [The activation energy (Ea) may be derived from the temperature dependence of the reaction rate using the Arrhenius equation.]

<span>addition reactions:</span> reactions in which an unsaturated system is saturated or part saturated by the addition of a molecule across the multiple bond.[E.g. the addition of bromine to ethene to form 1,2-dibromoethane]

<span>alkaloid: </span>organic substances occurring naturally, which are basic, forming salts with acids. The basic group is usually an amino function.

<span>allyl group:</span> a group containing 3 carbon atoms and a double bond [C1=C2-C3, where C3 is called the allyliuc position or allylic carbon atom].

<span>allylic rearrangement:</span> the migration of a double bond in a 3-carbon system from carbon atoms one and two to carbon atoms two and three,

<span>e.g. C1=C2-C3-X X-C1-C2=C3</span>

If the enthalpy change of a reaction in a flask is δh = +67 kj, what can be said about the reaction?
ziro4ka [17]
Answer : Normally in any chemical reaction, if the enthalpy change i.e. ΔH is positive which means it is greater than zero then it can be called as an Endothermic Reaction.

Whereas, the system under study is absorbing heat that is produced during the reaction. So if  ΔH  is found to be positive then it can be called as endothermic reaction.

which caused a change in matter. Select each procedure that is likely a chemical change. Salt crystals were crushed into a fine
olga55 [171]

Procedures that are likely a chemical change are:

- Bubbles were produced when iron was placed in acid.

- Two liquids were combined, and a solid appeared

- A white substance turned blue when water was added.
