Answer:
2-methylene propylbenzene
Explanation:
The Wittig Reaction is a reaction that converts aldehydes and ketones into alkenes through reaction with a phosphorus ylide.
The ketone in this case is 1-phenylpropan-1-one. The provided phosphonium ylide is shown in the image attached. The reaction involves;
i) alkylation
ii) addition
The product of the major organic product of the reaction is 2-methylene propylbenzene.
Answer:
The type of reaction is a single-replacement reaction.
Explanation:
Mg switches places with H, leaving H by itself.
Explanation:
3+3+6=12 is the three numbers adding up to 12
The mass number of the daughter atom formed from the alpha decay of a certain radioactive atom that has 90 protons and 142 neutrons is 228.
<h3>What is alpha decay?</h3>
Alpha decay of a radioactive material is the release of an alpha particle that posseses mass number of 4 and atomic number of 2.
According to this question, a certain radioactive atom that has 90 protons and 142 neutron undergoes alpha decay. This means that the mass number of the daughter atom will be as follows:
Mass number of radioactive atom = 142 + 90 = 232
Mass number of daughter atom = 232 - 4 = 228
Therefore, the mass number of the daughter atom formed from the alpha decay of a certain radioactive atom that has 90 protons and 142 neutrons is 228.
