Answer:
1) acetylide
2) enol
3) aldehydes
4) tautomers
5) alkynes
6) Hydroboration
7) Keto
8) methyl ketones
Explanation:
Acetylide anions (R-C≡C^-) is a strong nucleophile. Being a strong nucleophile, we can use it to open up an epoxide ring by SN2 mechanism. The attack of the acetylide ion occurs from the backside of the epoxide ring. It must attack at the less substituted side of the epoxide.
Oxomercuration of alkynes and hydroboration of alkynes are similar reactions in that they both yield carbonyl compounds that often exhibit keto-enol tautomerism.
The equilibrium position may lie towards the Keto form of the compound. Usually, if terminal alkynes are used, the product of the reaction is a methyl ketone.
Potential energy is not in motion, which means the roller coaster wouldn't be moving. do therefore it is kenetic energy because that means movement energy. hope this helps
Answer: A. Internal energy : May be viewed as the sum of the kinetic and potential energies of the molecules
B. Latent heat: The internal energy associated with the phase of a system.
C. Chemical (bond) energy : The internal energy associated with the atomic bonds in a molecule
D. Nuclear energy : The internal energy associated with the bonds within the nucleus of the atom itself
Explanation:
Internal energy is defined as the total energy of a closed system. Internal energy is the sum of potential energy of the system and the kinetic energy of the system. It is represented by symbol U.
Latent heat is the thermal energy released or absorbed by a thermodynamic system when the temperature of the system does not change. It is thus also called as hidden heat.
Chemical energy is the energy stored in the bonds of molecules.
Nuclear energy is the energy which is stored in the nucleus of an atom called as binding energy within protons and neutrons.
Explanation:
Density of object = gram/volume
= 100 g/ 5 cm³
= 20 g/cm³
