Answer:
The transition elements have their valence electrons in two different sets of orbitals that are (n-1)d and ns. Thus, transition elements show variable valencies due to the involvement of penultimate d shell electrons.
Explanation:
Answer is: branched alkene.
Carbon atoms can be
arranged s<span>traight chain, branched chain and ring.
Hydrocarbon is an organic compound consisting of hydrogen and carbon.
In straight chain carbon atoms are
bonded with only two other carbon atoms in elongate chain.
In branched chain at least one carbon is bonded
with more than two other carbon atoms. In this example </span><span>2-methylpentene</span><span> second carbon atom is bonded with three carbon atoms.
Ring chain hydrocarbons are cyclic hydrocarbons.</span>
The train cars moves in the same direction when the engine car begins
moving to the left.
<h3>What is Law of magnetism?</h3>
The law of magnetism states that like poles repel and unlike poles attract.
In substances which have magnetic field, they are known to attract each
other.
The engine and train car are highly magnetized which results in them
moving in the same direction when they are in close contact with one
another.
