Electrophilic addition quiz: 3 questions
Three questions on the Electrophilic addition card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
The positive charge on X is transferred to the carbon-carbon bond, forming a ______ during the formation of the C-X bond.
Answer
carbocation. The positive charge on X is transferred to the carbon-carbon bond, forming a carbocation during the formation of the C-X bond. From the Electrophilic addition article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Haglaz. Haglaz 40 · Electrophilic addition 36 · Acid anhydride 31 · Alanyl-tRNA synthetase domain containing 1 16 ATK in WikiCards.
Which of these Wikipedia articles is read the most in a year?
Answer
Haglaz. Haglaz 19,000 · Acid anhydride 13,000 · Electrophilic addition 6,600 · Alanyl-tRNA synthetase domain containing 1 140 Wikipedia reads over a year.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- The driving force for this reaction is the formation of an electrophile X+ that forms a covalent bond with an electron-rich, unsaturated C=C bond.
- The positive charge on X is transferred to the carbon-carbon bond, forming a carbocation during the formation of the C-X bond.
- In the second step of an electrophilic addition, the positively charge on the intermediate combines with an electron-rich species to form the second covalent bond.
Why it is Common
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Electrophilic addition article was read about 6,600 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 36 and blocks with 13: each hit it takes is cut by 5 %.
How to get Electrophilic addition
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
